So car runs good everything is checked that I can check and test. Now it idles fine once warm and a little rough when cold but my problem is that the ecu now does nothing. The air idle control screw works sort of but really only when it is pushed all the way in it wants to die. No vaccuum leaks or gas problems I have 2.3 approx CO. Timming is good
What else to check?

Mpstein

It could be a couple of things. I had a bad AAV and it was not timed correctly, then when timed and the AAV in and working, the ECU actually started showing how it could control mixture, and the TB needle valve actually worked to set mine at 950 rpm. But there was one more problem.

Check your plug wires. cyl3 wire needs to be AWAY from the MPS. The power to the plug is so strong that it screws up the MPS so that it kills acceleration from idle.

Mine died all the time when I had the wire near it.

Routed it under the tb tubes to the injectors last week.

I drove the car 100 miles today and it never missed a beat.

I am driving it hard and she comes back for more. That wire can be a real killer.

Good luck!

John
