I recently bought a 2002 Impreza wrx and was changing the spark plugs (Had the battery disconnected) the car was running perfectly fine before but i had to remove the Injen cold air intake to get to the spark plugs. After i had everything back together the car wouldn't start i assumed it was my spark plugs so continued to diagnose the problem through them then i figured out that it was the MAF. The car only runs in limp mode while the MAF is disconnected and doesnt start when connected. how do i fix the problem? I cleaned the old MAF that didn't work so i got a new one. The car also has a air flow converter Im not sure if that has anything to do with this but i thought i'd also put this out there.
