Car sits at idle when I try to hit it, it acts like it wants to stall then it goes. When I shift into 2nd and the rpm's drop it does the same thing. But when the rpm's don't drop ( when I keep them at 2000 or higher) it does not do this.

Also was driving at 40 or so car stalls and will not start....waited 2 hrs and it turned right over.


HELP!!!

Im not sure about the other things but when you start it up and try to go... is the motor cold? I think all 5.0's do that if you just start it and try to go....

when was the last time you changed your fuel filter? ive also seen fuel pumps "heat soak" and start dropping pressure after driving awhile. my $.02

krd005

probably been awhile for the filter. I will look into changing it

check fuel pres. after its hot too, thats what it sounds like to me

i know this is a dumb question but how would I go about that one?

Buy an adjustable fuel pressure regulatora and a liquid filled gauge. Hook it up (5 minute install) and than you can read/adjust your pressure.

There are a few companies who sell AFPR's... BBK, Kirban, Aeromotive, etc.
