Hello all, I have a 2001 Dodge Ram 5.9 that all of a sudden will not idle after it warms up. I have tuned it up and replaced the TAC. Also I have checked the map, and tps. There are so many sensors on this engine that I don't know where to start. One more thing, when the engine warms up and while driving if I let the engine coast for a second and then ease on the gas it kicks back one time. The idle problem starts when I put the truck in to reverse and as the engine warms up more it then won't idle in forward either. Any help or suggestions would be appreciated.
