there is a couple people with simuler problems but nothing exact. ok first off i start my car and put it in reverse.... and booom, it hits so hard i think my mffler is going to fall off. is it maybe and engin mount?.ok then if i put it in park or nutreal it will rev up to 2500rpm , then while im driving around 15-20mph the rpms wil jump up and down and it sputters and if i let off the gas it will stop and it will also happins around 30 to 40 and 50to 60. i tried cleaning out the throttle body and got a tune up. so if any one can help me out that would be sweet. thanks.&nbsp ; code p0105Edited by: rmitchell1741

1) Search "reverse Slam" (be sure to select "All forums")
2) Clean EGR valve
3) Check for vacuum leaks around throttle body and intake manifold
4) Has ECTS ever been replaced? If not, do so now. Also replace connector.

no codes? high rpms prob. intake gasket spray carb cleaner around cylinder 1 and 2.
