mechanic gave up
I posted my problem on Ram 2nd Gen with no responses. Any help would be appreciated.
My 01 Ram 1500 5.9L starting chugging and missing while driving engine light came on too.
I had wires, cap, plugs, seafoam, with no change. Had OBD done with bad #3 injector code, so
replaced it, no change. Ran OBD again now saying misfire on #1 cylinder. Checked #1 injector, spark
and plug all good. The local mechanic gives up and Im at a loss. Thinking maybe plugged fuel rail but
tired of guessing and losing $$$.
Any help???

They had problems with the plenum gaskets on those trucks, but I don't know if that would cause your problems. Both the 1 nad 3 cylinders are on the same side so maybe it is. Troubleshooting over the interent sux.

RE: mechanic gave up
did the mechanic just use a handhled obdII scanner or did he hook it up to a diagnostic machine. sometimes the hand helds will not go into the same depth. like todd said i would have them check the plenum gasket this is not that hard to check.

RE: mechanic gave up
Before you pull the top end apart, pull the O2 sensor wire & see if it throws a code.
I know this is an older car, but the wire to the O2 sensor burnt off & it started acting exactly like you describe. But it wouldn't throw a code. Changed the O2 sensor & fixed the problem.
Try that first before you pull it apart. Easy & inexpensive test.

Make sure your crank sensor wires did not get damaged or unplugged. An O2 sensor will throw a code. I had one in the shop about 3 months ago doing a very similar thing. It wouldnt run in reverse either till it warmed up. If it is the sensor they are a bear to change. Have a competent shop check out the sensor for you and you change it.

Hmmmm, I had a similar thing happen on my '01 Quad Cab. Ran fine at idle, started easy, no codes, just a intermittent miss at speed.
So, at 80,000 miles I figured it needed a tune up. Found out the coil wire had burnt in two under the coil bonnet. I was running the wiring & tugging slightly on the coil wire & it just kept giving...............til I had the end of it in my hand.
Surprise, surprise, surprise.
Finished the tune up (including a broken rib) and the truck runs like a top now.
Check the inexpensive things first.
