Question about Dodge Ram 2500
I have a 1997 Dodge 2500, 5.9L (360ci). I've Checked the TPS, MAP, the Idle control module. I've checked Fuel pressure, both at an idle & taped the gauge to the windshield to see what it was doing going down the road. Fuel Pressure and regulator appear to be good. I've checked the Cad. converter, it too appears to be good. I've replaced the Plugs, wires, cap & rotor, still to no avail. Not sure what else to check? I do not know how to reset the computer, but not sure that's what needs to be done.
Try unplugn it for a few may clear up--older cars get stale--it may need to be replaced cause the injector drivers are worn--but reflashn it may renew it-------a gud mech w the equip for that model can do it--a data stream run is important also--a store code reader doesnt show evrything--

I'm pretty sure it sounds like the seal under you fuel pump is bad I had a buddy whose truck was doing the same thing and we just replaced the fuel pump which came with a new seal and the fixed it I guess with the fuel pump seal bad it was letting air in and screwe everything up

Check the TPS. If you code the ECU there might be a P121 stored in the OBD2 port. If tere is no code the a cloged converter will be your best bet.

Hello! Although the Throttle Positioning Sensor (TPS) has been changed the symptoms are pointing at it...When the new one was installed was it mounted with the throttle valve held shut; Then rotated counterclockwise until the mounting holes lined up? Send a comment...Guru..saailer

check timing make sure it;s ok . second check your exhaust system if it;s close , start accilerate for 3 min. then look all exhaust pipe (silencer) if there is difrent coler . check Oxgen sensor it;s ok .
and if you have no enough fuel presure try close the return line temporary . maf, sensor only when there it is highand low accilerator.

Rough on idle when the engine is warm means there are many areas to be checked and it can start with the ECM , the fuel pump and more likely the sensors, check the throttle valve, the camsensor which can be set off which might need a correction. Also the vacuum feed for auto advance needs to checked.
