i hope someone has an easy fix to my problem...my 99 GT has recently started to rev too high at start up. half the time it is fine and the half the rpms jump to like 2500 and the engine just races. if i turn the car off and restatrt it immediately, the revs drop back to about 700. also, sometimes while sitting at a light the revs will just go up and again i have to turn the car off and re-start it. any suggestions?
