Picked up a 93 del sol by the noise, it sounded like a timing jump. Got it apart timing was on point. Fixed all the codes, but only a 4 flash remains for crankshaft position sensor, so slapped in a new distributor and no change. Iam absolutely stumped. Has new idle valve and a new fitv valve. Checked for vacuum leaks with spraying water on the intake. Tried 4 throttle bodies. Checked for change unplugging all manifold sensors which had some change but nothing conclusion.. pcv has vacuum. Just more stumped about no throttle response, and high idle. Shift to drive it drops to a steady 2k rpms.

have you verified that your throttle position sensor is set to 0.5v at idle, MAP sensor old or newer?
