I have a 2001 Porsche Boxster 2.5L engine / 5 speed manual. I recently got a check engine light, the codes are P1126 and P1133 (couldn’t find P1133 in my manual). I have heard it could be fuel cap, vacuum leak, but my investigation tell me it might have to do with the O2 sensor/s. Gosh now is it the front or rear O2 sensor and which side??? Can you help me figure this out?
Thanks,
Dennis
