my car has the dredded idle problem, it has an e-cam and small paxton blower. It will keep 15 pounds of vac if i hold the idle at 1000 rpm. Without giving it some help with the pedal, the idle and the vac gauge are all over the place. I tried to raise the idle with the screw on the throd.body but it seem the computer just re-adjusts it to 800 rpm where it will bearly run on its own. Any one have some thoughts??? There are no codes present on the computer.
