When I start the truck sometimes it will idle fine and then sometimes it won't idle. It will die and not run. I replaced MAP Sensor and did not solve the problem. Does anyone have any suggestions of what the problem could be?

have you tried changing the fuel filter? its relatively cheap and easy to replace and if it doesnt solve the problem you changed a filter that probably should be replaced regularly any way, Russ.

Thank You Russ. the fuel filter Is Ok I Change It Every 20.000. This One Has 1.800 On It. Thanks Derrell

Mine was doing the same thing, replaced the IAC and all is well. I will tell you though that we had to do it 3 times before we got a good one. Save yourself some trouble and start out with a Mopar part.
