M7risgood Posted May 18, 2018 Share Posted May 18, 2018 2009 Subaru Legacy PZE. Started having little acceleration but you could get it to 45 MPH. Auto zone read code and it was bad CC. then Before I changed that it wouldn’t go over 30 MPH. Changed CC (front one) and still same situation. Then I changed 02 sensor and the AF sensor and still same situation. I changed the oil today and attempted to clean MAF sensor. Reset the computer via unplugging battery, codes are gone, but car still runs the same....... WTH???? Link to comment Share on other sites More sharing options...
