Well shit I replaced my TB with a new/used one off a runing car and the reving up and down stoped. But when I took it back off to clean and paint it I broke the vac. fitting for the map. So I just put my old one back on While I waited for the JB weld to cure and the reving was normal. Drove it in stop and go trafic for almost 2 hours and it idled fine. Had to of been a vac. leak or a short in the wiring. Hopfully it won't come back. thanks for the help
