I have a 2008 dodge ram 1500 3.7l Truck fires at key turn however rpms rev up and down and truck shuts off right after two to three revs ups .. if i press the gas trucks rmps go high but truck sounds very rough, let go of the gas and trucks rpms go way low and it shuts off
Gerardo Duron there are just to many variables. Things like a bad O2 Sensor to problems with the Throttle body or bad IAC valve, bad fuel pump and many other things.. Your best bet would be to scan the OBD (try Autozone etc. fro free scans) and see what codes it throws. Let us know what you find out.
