I don't know how to explain it really but the engine lopes...idles up and down up and down. This usually happens when the car is warm. Like drive to town...then shut it off...go in Walmart...come out and then it does this and will do it all day as long as you have waited long enought but not so long that it completely cools down. I can't find a thing wrong with it. As a side note..I have the dreaded bank 1 to lean code off and on all the time and can't figure that out either. It does not seem to be related to when the light is on or off. It is now my daughters car so I have to get it fixed soon.
Thanks for any and all ideas on this! I'm stumped!
