lt1 map sensor circuit high code 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.
