ive read all the threads and im mechanicaly able. im gathering that it is the pre cat o2 sensor heater failur. im gona look into it and see what up with it i went ahead and cleaned the mass airflow sensor thinking that was the problem because at my work Advanced auto parts the OBDII spit out p1135:manfacurer contrl. FUEL AIR METERING.... any who thats how it was spelt to the MAF cleaning increased performance but i cleared the codes and it came right back on in like 2 mins. so help please advise from the pros please.
