I'm new here and have a new used 2002 Boxster Base with 140K
So far I have replaced plugs, MAF, Air/Oil Seperator, Water pump, coolant, oil, filter, oil filler cap , and air filter and it's now down to these two remaining codes. I also have run two bottles of Techron through on two different occasions. I am still getting the CEL and these two codes: 1128 & 1130 I have read a number of threads on these forums but there doesn't seem to be any consensus on what to do next to solve the issue. 1. Oxygen sensor? 2. Fuel cap? 3. Vacuum leak? 4. Fuel pressure? 5.Fuel injector? Any help is appreciated! Thanks! __________________ This post was auto-generated based upon a question asked on our tech article page here: Porsche Boxster Fuel Injection Fault Code Reading / Diagnosing Problems - 986 / 987 (1997-08) - Pelican Parts Technical Article |

Best bet, check when the fuel trim is skewed. Is it lean at idle or only under part load? Once you figure this out you will be able to narrow down the causes.

Thanks Nick.
I think I need the Durametric to check this, correct? I only have a dumb little code reader and apparently just clearing the codes doesn't make the problem go away, huh? This is a great little car, though. Fun to drive, pretty easy to work on (even for an idiot like me) and Pelican is a life saving resource! Thanks |
