Mass Air Flow Sensor Question!!
I cleaned my TB and MAF sensor today with some CRC throttle body cleaner. I reassembled everything and the truck is idling very rough, terrible acceleration and the engine and exhaust sound horrible. I took everything apart again and all the connections are all in place. I had a friend press down on the gas pedal when the truck was not running and the TB moves back and forth (fully open on full throttle, then when letting off throttle closes completely for a second, then hangs a little less than 1/8th open - i think this is normal). I re-cleaned the MAF sensor. Still the same problem. Did I wreck my MAF sensor or is this something with the TB? The wires on the MAF sensor all look good, but I can see some minor surface scratches on the metal. It is NOT throwing any engine codes. I disconnected the battery for half hour and pressed the gas pedal to clear the system. Anyone have this same issue?? I might go buy a new sensor at the wreckers tomorrow and see if that does anything.
