when i start the truck sometime sounds like alot of compression and then sometimes sounds like regular cars do then the other problem is when i start the truck the idle reves and decelerates on it own and sometime stalls out, I can drive the truck but must shift to neutral at stop signs and keep the rpm's high. Maybe bad injectors i did put a new fuel pump in the tank and new cap rotor wires plugs and coil. HELP!!! I am running out of ideas!

thanks

You may want to look at a couple of things. First connect a vacuum gage to see what your engines vacuum is, if you have low vacuum then you have a vacuum leak that needs to be tracked down. If you have good vacuum then check out the idle air control valve, you may be able to clean the valve and free it up or if that doesn't work you may look at replacing it. Good Luck.

I've had the same problem on my 1995 Ram 1500 V6 3.9L . I would appreciate it if you'd let me know what the fix was. Thanks!

P.S. I've replaced the IAC already and the truck seems to use way too much fuel and gumming up the intake.

Suggested Repair

Connect a vacuum gauge and check engine vacuum. Low vacuum points to a vacuum leak that should be located and repaired. If vacuum is normal, clean the idle air control valve or replace it if cleaning does not steady the idle.

Conversation Summary

The owner of a 1995 Dodge Ram 1500 reported an erratic idle that rose and fell on its own, occasional stalling, and a need to hold higher RPM at stops. A fuel pump, cap, rotor, wires, plugs, and coil had already been replaced. An expert advised checking vacuum for a leak and cleaning or replacing the idle air control valve. Another owner of the same truck said the valve had already been replaced and fuel use was high, but no confirmed fix followed.
