Got the '94 dodge 5.2 liter for a steal. told me there was a hesitation in initial acceleration and does the same in overdrive at a certain RPM. Said it didn't start until after he changed plugs, wires, and distributor cap. (hopefully not related.) Put a new EGR and O2 Censor on it and i think the hesitation is completely gone. but the shudder is still there. either at a certain RPM or just when i'm trying to maintain speed with the slightest of throttle pressure. I turn off the overdrive and it stops for the most part. until it reaches a certain RPM again. but applying torque through acceleration certainly helps. Please no abbreviations cuz i won't understand most of them. Thanks.

 

sounds like a misfire, indicating that changing the plug, cap, and rotors likely caused it.

id replace the plugs with a good set of coppers- autolite, champion or NGK.

 

try the torque converter lock up selonoid. explains every problem you have, i know because i have the same problem.

 

you say your having the problem? not sure it will fix it?

 

the exhaust does smell like there may be some unburnt gas amongst it. thanks for your input

 

At what speed?

 

When mine was doing that trick, it was an engine miss, due to fouled plugs, due to a blown plenum gasket..... Pull the plugs, see what they look like. Cap and rotor as well.

 

i have a plug that i can't get out. thinking someone else couldn't either. hoping it's old and fouled. maybe the problem. would that effect power as well?

 

Sure wood. not to mention fuel economy.....

 

Spray a bunch of penetrating oil in plug well, then back it out as far as you can, then screw it back in, then repeat, and the oil should eventually work its way down the threads and you can remove it.
I've done this before on a chevy from Michigan, talk about a rust bucket.
