Im not sure how i should continue to diagnose this code, i replaced old sensor iwth a known good one and had no difference, code is still present for both engine and tranny codes with a gm tech 2.

i have tried spraying around my intake with carb/choke cleaner to see if the idle would spike showing i had a vacuum leak. i cant notice any really big difference, if any at all.

i cannot get hte car to idle properly unless i unplug the maf, then the car will idle at approx 1800rpm.

i had the iac counts checked and that was working properly.

any input would be very helpful, thanks guys.
