today...

tested air flow sensor, both resistance and voltage. Perfect.

When I first turned on key, koeo, I got 70% DC. After the car sat and warmed up, I got DC varying around 65% while running. Then it went to varying around 10%. No change in the way the engine was running.

Turned engine off, koeo, 10% fixed DC. Pressed down air sensor plate...went to 70% fixed. Let plate up...back to 10% fixed. BUT, air flow pot tested perfectly and had continuity to computer. Unplugged temp sensor...went to 70%...plugged it back in...went to 10%...unplugged idle speed control...went to 70%...plugged it back in...went back to 10%.

All the while it's stuck at +2ma on the EHA anytime it's running or koeo.

After the car sits a while it will go back to the proper 70% koeo.

sigh.......
