Porsche Boxter 986 2.7 smoking still after AOS Change
Hi Guys,
Has anyone know a way around diagnosing the problem I have here.
The car had a ton of smoke coming out the back - replaced the AOS - it still is smokey but not as much - upon observation it seems like an unburnt fuel smell. Changed the oil - changed the coolant - replaced sparks and O2 sensors. Done a diagnostic test with the durometric software - got the following error codes. Cleaned the plenum internally and replaced the throttle body.
PO300 - Porsche fault code 62 - Misfire damaging to cat converter
PO301 - Porsche fault code 63 - Cylinder 1 misfire damaging to cat converter
Can anyone shed some light on next steps??
Thanks in advance.
