nnblackgt Posted September 7, 2013 Share Posted September 7, 2013 My legacy gt started knocking when it first turns on at idle but its not constant sounds like its coming from the back but not sure. check engine light is on and cruise light is flashing. pulled up codes P0021 and P0113. i did an oil change nothing, changed maf sensor nothing, changed a ripped up alt, ps belt nothing. I believe those codes are camshaft sensor timing advanced and maf is bad. but not sure what to do now. Link to comment Share on other sites More sharing options...
ttnio Posted September 7, 2013 Share Posted September 7, 2013 It took about 50 miles before my P0011 code clear. Of course, I did the oil change. Link to comment Share on other sites More sharing options...

SpecBamf41 Posted September 9, 2013 Share Posted September 9, 2013 I just got this light combo after starting the car without pluging maf back in. Hope it clears itself as did the other guys. Sent from my S3 BNR18g on 93oct Link to comment Share on other sites More sharing options...
