hmm slightly puzzled, acts like iac is bad -(unplugging iac makes no change hot or cold engine) i had an extra , cleaned it and put it on
got voltage at connector to iac, resistence is within spec, applying voltage to iac i can see the plunger moving and hear the solenoid click
cel comes on cold, goes away warm, car idles warm - not normally, slightly rough and under speed, but idles
now what?
