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.

POST 1 / ORIGINAL POSTEROriginal post

1998 Boxster 150,000 miles. The idle when warming up will wander from 500 to 1200 RPMs. After about 5 cycles, it settles in at around 900 RPM. Just took my first drive in the car and when it warmed up, the idle wanders when coming to a stop. At one stop it died. It does not idle rough, just wanders. No codes appeared. I have replaced the plugs, coils, oil and filter. I need some help on where to looking to solve the idle issues. Thanks!

POST 2Original post

How do your fuel trims look like, are they far from normal? I would start by checking and cleaning the MAF if fuel trims are negative. Or checking for vacuum leaks if the fuel trims are positive.

POST 3 / ORIGINAL POSTEROriginal post

What tool do I need to check the fuel trims?

POST 4 / ORIGINAL POSTEROriginal post

I do have a scanner if that is the tool to read the trims.

POST 5 / ORIGINAL POSTEROriginal post

Cleaned the TB, MAF sensor and IAC. One of those fixed the problem.
