I throw a P0300 from time to time (I've been told there is a TSB on this) but I also occasionally throw a P0420 (catalyst efficiency) code. However, I think I've only seen the P0420 with the Trackey. Anybody else seen this code pop up?
The P0300 is a known issue which is fixed with the "crankshaft sensor relearn"ChuckP said:Stock exhaust sans restrictor plates. I'll have dealer look into both codes. Thanks.
