Man, this truck is driving me crazy. I start my truck and it does not idle. It will start at 700 rpms and then does up to 1300 rpm then down to 3-400rpm. Then back to 700. Does anyone know what this is? SOmetime I put the car in drive and floor it and it will not move.

Weird.

HELP

Dennis,

I am not an expert, but I may or others may be able to help, but we need more info.

Does the engine throw any SES codes? How does it run when you can get it to move? Is it shifting hard when you get on the throttle? Are there times when you start it, and everything runs fine as if nothing is wrong, and other times it runs poorly?

Pedal assembly.

Also have a look at the fuel pressure regulator screen.
LOOK HERE if you need to learn how to do it....

Does not give SES codes. Does not run bad once I get it running and does not shift hard.
