Ok, so i drive a 06 cobalt ss and i have been getting the dreaded reduce power signal. the codes are p0102 MAF low input, p0036 o2 sensor heater control, p0030, p0135 o2 sensor heater circuit malfunction, p0141 o2 sensor heater circuit malfunction, p0443, p0135, p0102, p0068, p0135, p0141, p0443. some are repeats ireplaced both o2 sensors, mass airflow and MAP sensor. I also cleaned the purge valve. I have seen 4 certified techs and no one can tell me whats wrong i need help!!!

 

Look at ure.02 ensor wiring make sure its not.melted.to.ure exaust. Make sure ure wiring is good frm pcm to connectors. Clean maf. If this don't help clear the codes, take power from the car. For 10mins. Restart the car. U should get the.code.quickly, start from ure first.codes then diag. From there.
