im haveing the same problem, and it does it kind right after the car has wormed up, driveing for about 2/3 miles, and just today the check eng. light came on, now sometimes it drive just fine, but when i put in in reverse the eng.(rpm) jump up almost to 3 1/2 - 4 grand, can you please help me out with this one,,, do you think its time to change the spark pluggs,, just guessing
It's almost certain to not be the spark plugs. If the check engine light is on, that means you have a failure in your emissions control system, which can sometimes be related to the transmission, which is what it sounds like you are having immediate trouble with.

You will benefit from the help of a good diagnostic technician, as it sounds like it could be a significant or complex problem.
