Yes.. but I tell you though.. I would hate to loose that sound my truck makes; it sounds like a mild cam and turns alot of heads when i pull up to them.. LOL!
So I'm thinking Exhaust.. if any.. like that said its the most likely... out of the two. You could try doing it the cheap way first; pull the exaust man off and Engine tune that bitch.. see if that helps.. put some oil there and see if comp test goes up .. or drains in the cyl

SYMPTOM/CONDITION:
Some vehicles may exhibit one or more of the following:
Using the Mopar Diagnostic System (MDS/MDS 2) or the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If other than mentioned Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present or if the above symptoms/conditions have been described by the customer, perform the Repair Procedure.
NOTE: This rerouting procedure should be performed before any other misfire, surge, or spark knock repairs are attempted.
PARTS REQUIRED:
1. Coil Wire Routing (Figure 1 and 2)
A. Remove the coil wire from the distributor cap coil wire tower terminal.B. Remove the coil wire from the rear five-wire clip, the center three-wire clip, and the front one-wire clip located along the lower side of the right valve cover.C. Install three (3) one-wire clips p/n 56028186 along the top and front of the valve cover. Use the studs of the valve cover retaining bolts (Figure 1).NOTE: Some applications may only have stud locations for three of the one-wire clips.
D. Route the coil wire starting from the ignition coil toward the distributor. Any excess wire should end up at the distributor end.E. Install the coil wire into the one-wire clips. This procedure may be easier to perform while the coil wire is loose from the valve cover (before the one-wire clips are attached to the valve cover studs).F. Cut the ignition wire convolute p/n 04364375 into three lengths 8", 4", and 3.25".G. Slit and install the three sections of convolute onto the coil wire between the one-wire clips. Install the 3.25" section at the front of the right valve cover. Install the 8" and the 4" sections along the top side of the right valve cover. This procedure may be easier to perform while the coil wire is loose from the valve cover (before the clips are attached to the valve cover studs).H. Route the distributor end of the coil wire down and behind the intake manifold, in front of the oil pressure switch (Figure 2).NOTE: The coil wire must be a minimum of one (1) inch away from any other ignition wires. This may require that the coil wire be routed under vacuum and/or wire harnesses in the right rear corner of the intake manifold.
I. Route the distributor end of the coil wire up the side of the distributor cap and onto the coil wire tower terminal.J. Position the original piece of coil wire convolute so it protects the wire against chafing with components at the rear of the engine.
2. No. 8 Cylinder Plug Wire Routing (Figure 3)
A. Remove the No. 8 cylinder plug wire from the distributor cap tower terminal.B. Remove the No. 8 cylinder plug wire from the five-wire clip located at the lower rear of the valve cover.C. Route the No. 8 cylinder plug wire over the rear quarter of the right valve cover (Figure 3).D. Position the original piece convolute from the No. 8 cylinder plug wire to prevent chafing at the right valve cover and with other engine components.E. Secure the No. 8 cylinder plug wire and its convolute in place with the hose to wire clip p/n 06503441. The small end of the clip is positioned over the convolute. The large end of the clip is fastened to a heater hose (A/C line on ZJ models).NOTE: make sure the No. 8 cylinder plug wire is secure and away from the coil wire and the no. 4 cylinder plug wire. Make certain it will not fall down and contact the cylinder head and or exhaust components.
F. Install the No. 8 cylinder plug wire to its distributor cap terminal.
3. No. 4 Cylinder Plug Wire Routing (Figure 4 and 5)
A. Remove the No. 4 cylinder plug wire from the distributor cap terminal.B. At the three-wire clip (located at the center of the lower side of the right valve cover), keep the two wires from crossing and chafing each other. Position the No. 2 cylinder plug wire in the top wire slot and the No. 4 cylinder plug wire in the bottom wire slot. Leave the middle wire slot empty (Figure 5).
C. At the five-wire clip (located at the right rear lower side of the valve cover), keep the plug wires from crossing and chafing each other. Position the No. 4 cylinder plug wire in a slot that will obtain the maximum amount of distance allowable from the No. 8 cylinder plug wire (Figure 6). Remove any slack in the No. 4 cylinder plug wire between the three-wire and the five-wire clips.NOTE: Earlier model five-wire clips look slightly different but the same wiring layout applies.
D. Route the No. 4 cylinder plug wire behind the transmission dipstick tube and heater hoses. On ZJ models this may not be possible due to the location of the bulkhead.NOTE: Make sure that the No. 4 cylinder plug wire is, at least one inch away from the No. 8 cylinder plug wire.
E. Install the No. 4 cylinder plug wire to its distributor cap terminal (Figure 7).
4. No. 7 Cylinder Plug Wire Routing (Figure 8 and 9)
A. Verify that the No. 7 cylinder plug wire crosses over the distributor cap and leaves the distributor cap between the No. 3 and the No. 6 tower terminals (Figure 8). This is the original wire routing for 1998 and prior model years.B. For 1999 M.Y. vehicles the No. 7 cylinder plug wire was shortened. Reroute the No. 7 cylinder plug wire so that it crosses the distributor cap and leaves the distributor cap between the No. 6 and the No. 5 tower terminals (Figure 9).NOTE: Make sure the No. 7 cylinder plug wire is, at least one inch, away from the No. 5 cylinder plug wire.
5. No. 5 Cylinder Plug Wire Routing (Figure 10)
A. Remove the No. 5 cylinder plug wire from its distributor cap terminal.B. Remove the No. 5 cylinder plug wire from the five-wire clip located at the lower rear of the left valve cover.C. Route the No. 5 cylinder plug wire over the left valve cover and in front of the breather tube elbow.D. Position the original convolute from the No. 5 cylinder plug wire to prevent chafing against the valve cover and any engine components. Secure the small end of the hose to wire clip p/n 06503441 over the convolute. Secure the large end of the hose to wire clip to the breather hose.NOTE: make sure the No. 5 cylinder plug wire is secure and away from the No. 7 cylinder plug wire. Make certain it will not fall down and contact the cylinder head and/or exhaust components.

I. Route the distributor end of the coil wire up the side of the distributor cap and onto the coil wire tower terminal.J. Position the original piece of coil wire convolute so it protects the wire against chafing with components at the rear of the engine.
2. No. 8 Cylinder Plug Wire Routing (Figure 3)
A. Remove the No. 8 cylinder plug wire from the distributor cap tower terminal.B. Remove the No. 8 cylinder plug wire from the five-wire clip located at the lower rear of the valve cover.C. Route the No. 8 cylinder plug wire over the rear quarter of the right valve cover (Figure 3).D. Position the original piece convolute from the No. 8 cylinder plug wire to prevent chafing at the right valve cover and with other engine components.E. Secure the No. 8 cylinder plug wire and its convolute in place with the hose to wire clip p/n 06503441. The small end of the clip is positioned over the convolute. The large end of the clip is fastened to a heater hose (A/C line on ZJ models).NOTE: make sure the No. 8 cylinder plug wire is secure and away from the coil wire and the no. 4 cylinder plug wire. Make certain it will not fall down and contact the cylinder head and or exhaust components.
F. Install the No. 8 cylinder plug wire to its distributor cap terminal.
3. No. 4 Cylinder Plug Wire Routing (Figure 4 and 5)
A. Remove the No. 4 cylinder plug wire from the distributor cap terminal.B. At the three-wire clip (located at the center of the lower side of the right valve cover), keep the two wires from crossing and chafing each other. Position the No. 2 cylinder plug wire in the top wire slot and the No. 4 cylinder plug wire in the bottom wire slot. Leave the middle wire slot empty (Figure 5).
C. At the five-wire clip (located at the right rear lower side of the valve cover), keep the plug wires from crossing and chafing each other. Position the No. 4 cylinder plug wire in a slot that will obtain the maximum amount of distance allowable from the No. 8 cylinder plug wire (Figure 6). Remove any slack in the No. 4 cylinder plug wire between the three-wire and the five-wire clips.NOTE: Earlier model five-wire clips look slightly different but the same wiring layout applies.
D. Route the No. 4 cylinder plug wire behind the transmission dipstick tube and heater hoses. On ZJ models this may not be possible due to the location of the bulkhead.NOTE: Make sure that the No. 4 cylinder plug wire is, at least one inch away from the No. 8 cylinder plug wire.
E. Install the No. 4 cylinder plug wire to its distributor cap terminal (Figure 7).
4. No. 7 Cylinder Plug Wire Routing (Figure 8 and 9)
A. Verify that the No. 7 cylinder plug wire crosses over the distributor cap and leaves the distributor cap between the No. 3 and the No. 6 tower terminals (Figure 8). This is the original wire routing for 1998 and prior model years.B. For 1999 M.Y. vehicles the No. 7 cylinder plug wire was shortened. Reroute the No. 7 cylinder plug wire so that it crosses the distributor cap and leaves the distributor cap between the No. 6 and the No. 5 tower terminals (Figure 9).NOTE: Make sure the No. 7 cylinder plug wire is, at least one inch, away from the No. 5 cylinder plug wire.
5. No. 5 Cylinder Plug Wire Routing (Figure 10)
A. Remove the No. 5 cylinder plug wire from its distributor cap terminal.B. Remove the No. 5 cylinder plug wire from the five-wire clip located at the lower rear of the left valve cover.C. Route the No. 5 cylinder plug wire over the left valve cover and in front of the breather tube elbow.D. Position the original convolute from the No. 5 cylinder plug wire to prevent chafing against the valve cover and any engine components. Secure the small end of the hose to wire clip p/n 06503441 over the convolute. Secure the large end of the hose to wire clip to the breather hose.NOTE: make sure the No. 5 cylinder plug wire is secure and away from the No. 7 cylinder plug wire. Make certain it will not fall down and contact the cylinder head and/or exhaust components.
3.9 Liter Engine Procedures
1. Coil Wire Routing (Figure 11 and 12)
A. Remove the coil wire from the distributor cap tower terminal.B. Remove the coil wire from the right rear five-wire clip, the center three wire clip and the front one-wire clip on the right valve cover.C. Install three (3) one-wire clips p/n 56028186 along the top and front of the valve cover studs (Figure 11).D. Route the coil wire starting from the ignition coil toward the distributor. Any excess wire should end up at the distributor end.E. Install the coil wire into the one-wire clips. This procedure may be easier to perform while the coil wire is loose from the valve cover (before the one-wire clips are attached to the valve cover studs).F. Cut the ignition wire convolute p/n 04364375 into three lengths. Two (2) at 4" and one (1) at 3¼ .G. Slit and install the three sections of convolute onto the coil wire between the one-wire clips. Install the 3¼ section at the front of the right valve cover. Install the two 4" sections along the top side of the right valve cover. This procedure may be easier to perform while the coil wire is loose from the valve cover (before the clips are attached to the valve cover studs).H. Route the distributor end of the coil wire down and behind the intake manifold, in front of the oil pressure switch (Figure 12).I. Route the distributor end of the coil wire up the side of the distributor cap and onto the coil wire tower terminal.J. Position the original piece of coil wire convolute so it protects the wire against chafing with components at the rear of the engine. NOTE: The coil wire must be a minimum of one (1) inch away from any other ignition wires. This may require that the coil wire be routed under vacuum and or wire harnesses in the right rear corner of the intake manifold.

No I just know it's not that.. I think i read that same TSB 10 times making sure i had it right..
But just throwing this out there.. check engine light is back off.. shutter is still present.. just not as hard as it was. Remember it's 'beyond a certain miss' when it triggers a CEL; so it could be missing ever so slightly to feel it but not trigger. I think that's what we are dealing with; maybee your is a little more progressed?
