New INFO
Here is what I have now........let the car run for over 15min. The idle dropped to 1100rpm at about 160*
at this point rev the car to 2000 rpm and get a small backfire on deceleration.
small miss across rpm band
Batt voltage good on dash
when this all happened the ECM will no longer allow me to do scans or watch the sensors in real time. Right before the computer locked me out I began to get some crazy readings (ex. intake air temp -15*) Would no longer read the MAF
When I first start it up I can get correct sensor readings.
Oh yes if I sit there with the key on and the motor off the computer will kick out odd codes and kick the cooling fans on and off numerous times.
