well i am stupid. last weekend i had my car detailed and yes stupid me had the motor sprayed off. the same day i had it done it ran fine, then i let it sit for a day without using it. when monday came i started it and it reved up like a high idle around 2k, i reved it more and it came back down and then started jumping up and down, goin from under 1k and up to 2k never stopping. ne of u guys have the same problem or know what is causing this? i work at a toyota dealer in the service part but its a smaller dealership so less budget, and none of the techs are familiar with supras at all and we dont have ne books on them so they arent much help. a couple of the techs said it was a vaccum leak but we checked it over real good and didnt see any loose hoses. any help will be appreciated.
