Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Thinking something to do with change from open loop to closed loop operation after 3 minutes (but no codes for O2 sensors)?

Frequently discussed actions (5)

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

  • Pelican Parts: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Was driving my 996 home when all of a sudden it misfired while driving, was able to restart and limp home. Have been in lockdown for ages so have done some wrenching, including: PARTS REPLACED: Cyl 6 coil pack, spark plug & tube (first codes read was for misfire cylinder 6). Fuel pump and fuel pressure regulator. Alternator and starter. Crank position sensor. Oil pressure relief spring & piston upgraded. PARTS CLEANED: Throttle body and plenum. IACV cleaned and checked with 9V battery. MAF cleaned. PARTS CHECKED: Y cable checked. Battery holds good voltage. Swapped to another battery no change in problem. No codes for misfire anymore. From a cold start, car idles 100% fine at 1000rpm no issues. After 3 minutes, revs drop, motor shakes, eventually stalls. Restarting when warm then goes straight to bad idle and stalling. No codes. Thinking something to do with change from open loop to closed loop operation after 3 minutes (but no codes for O2 sensors)?

POST 2Original post

I'd also look at the crank position sensor, they tend to fail when hot, but then are just fine cold.

POST 3Original post

Cleaning the MAF can have consequences. What type of air filter? Was it oiled?
