Hey guys, Newbie here. My '01' Ram 2500, 360, develops a miss shortly afte start-up. If I throttle it for a few minutes it will work through it and run fine the rest of the day (if it's warm), or until I shut it off and start it up again (if it's cold). My thought is that it's associated with the air/fuel mixture, given the symptoms, and I'm leaning towards an oxygen sensor.
It carries the recommended fuel pressure, and the injectors are all working. It occurs everyday, but never throws a code. Just thought I'd look for some insight before taking it to the shop.
Thanks for any input,
Bob

 

Sounds like a bad Throttle Position Sensor. "TPS" Also you might want to clean the TB and all sensors.

 

Problem solved, finall threw a code after several weeks. Oxygen sensor bad.
