So my 15 year old son sold his 4 wheeler and got his first car. 86 GT Coupe. He is so Happy.
New fuel pump, clean out all the lines and the tank, fuel dizzy, injectors, etc. We did all this because we had no idea how long the car has sat and the Dr Pepper in the tank proved it's been a while.
A few hick ups aside and the car comes to life. Runs Great! in fact. Except it idles around 3k-3500 rpm.
I have searched for a vacuum leak. No dice. Adjust the screw on the TB all the way in it still screams. Turn it out and it screams more. Throttle cable is not pulling on it. Disco the cold start injector. No change. Check the timing. Nope.
