Hi i was hoping that you well informed bunch could help with these codes, My GTV has been into 2 different garages and neither have an idea what is wrong i keep being told that they can't find anything wrong with the car. I've 6 different codes
(1) PO300-RANDOM MISFIRE DETECTED,
(2) PO301- MISFIRE DECTECTED, CLYINDER 1,
(3) PO304 MISFIRE DETECTED CLYINDER 4,
(4) PII73-ADDITINE MIXTURE CORRECTION,
(5) PII51-OXYGEN SENSOR, BANK 2 SENSOR 1 SIGNAL,
(6)PII72 MULTIPLICATIRE MIXTURE CORRECTION.
All the garages done was to clear the codes and within days the light comes back on. Any ideas? I was thinking maybe air flow meter or possiblely the cat, but these are just a leymans ramblings.
Cheers for the help
