1995 Ram360 V8 w/ mysterious engine problem
I Have a 1995 Ram 2500 with a 360 (Z code engine) that has a mysterious engine problem. It hesitates at first on acceleration, then if you quickly let off the throttle it gets worse, or sometimes dies. It also hesitates badly when you are trying to drive slowly (like in a drive through, or a parking lot), and when trying to reverse. The problem seems to be stronger when the truck is at full running temp. It also seems to lope or buck (if that makes any sense) while at crusing speeds(most noticable at or around 45mph, then again around 60mph) almost like it is hesitating.
I have replaced the fuel pump assembly, installed a new O2 Sensor, replaced the PCV valve, Installed a new reinforced intake plenum cover (from Hughes) along with new intake gaskets, checked my MAP and TPS sensors, Checked that all my injectors are working correctly and ohm correctly, replaced my spark plugs/wires/cap & rotor, ran sea foam (2 cans) in the fuel, and another full can through the vacuum lines/intake manifold. None of this did a thing, I still have all the original problems. Oh, and I have no check engine light on either.
Has anyone experienced a problem like this, or know what might be causing my nightmare?
Thank You

Sounds like you have some sort of vacuum leak. The increased presence of air is countered by the enriched state of the motor(when cold). This is probably whythat symptom is more evident at operating temperature. Rough idle?
Just a suggestion but have you checked your cat? Seen them do some wierd things to vehicles.
