Hi guys, I have a wierd idle problem.

I noticed it this morning during cold start up. The truck would kinda shake/jump on what seemed to be each piston firing off.

And when the truck is in D and you have your foot on the brake it jumps and shakes like it ready to run a race. :rolleyes:

Know what I mean and how to fix it with EFIlive?

Thanks alot guys

It shakes like a hot rod w/ a HUGE cam in it...maybe thats a better description :)
