Ok, car ran great, installed the intake plate and then the high idle problem occured, removed plate and the same problem, checked all gaskets and cannot find any vaccumm leak anywhere on the vehicle. When the engine warms up it will idle up to 1500rpm, and the iac drops to zero and I checked and it is fully closed. adjusted the air bleed srew all the way and the iac remains at zero. This would tell me that there is a vaccumm leak, but I have checked 5 times. Fuel trims seem to remain pretty close to 128, iac has been replaced. Any help would be great... Thanks
