Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hey all relatively new to forum so bare with I recently bought a 2002 Boxter S great car love it 18,000 miles Problem is already flashing like 1135 code it currently has 27000 i wouldn't think the oxygen sensor would be bad already are there any things i should be looking at ? I do notice intermittently it wants to cut out at around 5000 rpm are these related at all ? Could it be the frecken ethanol we are getting in fuel ?

POST 2Original post

Sounds like another MAF sensor detected at the Bank 2 O2 sensor.. Try simply unplugging the MAF cable and see it it cuts out at 5K RPM.. I read too many places that a dirty or defective MAF can cause the P1135 at the O2 sensors.. If it is the MAF, and you replace it, you need to have the codes cleared.. I'll shut up now and let someone with more expertise help..

POST 3Original post

Everyone gets ethanol in fuel (or will until the politicos decide we have more gas than corn). Are you sure the code is a 1135? I ask because P1135 it isn't listed as a code in the DME book for the 7.2. Flashing? Exactly what is flashing? The CEL? Flashing CEL is really serious problem. Get the codes read and don't drive it until you know exactly what the problem is.

POST 5 / ORIGINAL POSTEROriginal post
