I bought another mp3 from someone who rebuilt the engine. Strangest thing happens, when the car is started, it continually rev's up to redline unless put into gear. After I unplugged the IAC, the car idles around 2500 with a shaky idle. I removed the egr, cleaned, and kept the solenoid off as well. I cannot for the life of me figure out the problem. Im betting its the IAC but im not sure how to test it. Also, what should the throttle position be set at for idle? as the throttle is slightly angled open when depressed
