The problem is the car will drop to about 500 RPM, surge to circa 2k, drop to about 400 RPM, surge back to about 2k, and then die. Also tries to die when stopped at lights/stop signs.

Trying various things to fix the idle problem...

Steps taken below:

Sprayed carb cleaner all over engine bay, no change. Problem still occurs.

Take off IAC, idles steady at about 3k. Replace, and problem comes back.

Take off the MAF, no change. Problem still occurs.

Take off the TPS, no change. Problem still occurs.

Any other options please let me know. I know that I have posted a couple times about this in various threads of mine, but i am consolidating it all in one place. I need to get this problem fixed - since I cannot really drive the car until I do. It has been down for a little over a month now during the engine rebuild and it is my only car.
