Hey guys,

On the way to schoo and back, I noticedwhen I drive my car and I take my foot off the gas, the car's idle at coasting rises and falls by itself and causes a very slight acceleration. By the way.. i'm AUTOMATIC. I think I read on here before that it could be the throttle plate sticking or something???? Could it possibly be the butterfly plate is sticking because of the cold weather?? But it hasn't happened until today and it's been cold for two weeks.

Any possible diagnosis. Please list any possibilies and fixes. Thanks.

There are a few possible causes for this prob. check out this vfaq link and it should help you get rid of surge

Hope this helps
