I replaced timing chain guide...car was running fine before this. Never had to adjust the timing...car was running fine. Put everything back together and now car idles high at 3500 rpms when starting. checked IAC valve, and throttle position sensor, but car still idles high. i also disconnected mass air flow sensor but no changes. What else could cause it to idle so high?
