Hunting idle for me ended up being the ICV. New Bosch part fixed it up. I also believe the airflow potentiometer was not helping the matter. I got a new one a week before adding the new ICV. Though, the ICV is ultimately what stopped the problem.

Thanks guys.

It has a new ICV, no change and it does 'click'. The old one was good as well.

I disconnected the line to the cold start valve and ran a line to my spare fuel can. The car wouldnt fire.

The loaner parts will be here on Friday. After that.....?

Valve adjustment?

Rotor off by a sprocket?

I did check the timing chain and its new and lines up with the timing marks at TDC. But in the process I removed the rotor and I think I might be off by a spline on the gear. Tomorrow Im going to smoke test the engine to look for vacuum leaks.

Check the o2 sensor, temp sensor, and airflow potentiometer if you haven't already. All are easy to test. Just got done with this same problem if you need explanations.

My Coolant temp sensor is off a little...at 90 degrees it Ohms out at 393. I believe target is 200 to 300 at that temp. Thats what I get for buying ebay no name sensors. New Bosch 02 sensor, new throttle plate and new fuel / air plate with potentiometer pre adjusted. Im going to test the pot switch just to make sure tomorrow. Loaner temp sensor, fuel pressure regulator and cold start valve on Friday.

I believe these are the correct ohms for the coolant temp sensor:

60c - 600
70c - 435
80c - 325
90c - 247 etc

Like I said mine is at 393.
