So, ever since before my rebuild, I've had idle issues. I changed my intake with the rebuild, But kept the same throttle body and MAFS. I know my MAFS is contributing, Because with it plugged in, I run lean. With it unplugged, I run rich. But what else could it be? vacuum leak? Idle air control valve? (very strong possibility). I'm really interested in fixing this, I can even bring the car by your house to let you hear it run, If that helps. Thanks.
