86subaru Posted November 26, 2010 Share Posted November 26, 2010 no codes, starts fine, but after it warms it;s fine, knock sensor seems to have a crack in it, Link to comment Share on other sites More sharing options...
wtdash Posted November 26, 2010 Share Posted November 26, 2010 (edited) Best 'guess': You're in 'limp/fail-safe mode' due to the knock sensor, which lowers performance....not sure why there's not a code?? A cracked KS needs fixed regardless - used or new ($50 online). Edited November 26, 2010 by wtdash Link to comment Share on other sites More sharing options...
