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.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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

Under normal use, the idling speed suddenly becomes higher, sometimes about 1000rpm, sometimes higher, do you have any car owners with the same experience? Which direction to go for maintenance, thank you for providing information

POST 2Original post

Do an e]gas calibration first. Key in ignition, turn key to on (not start). Wait 60 seconds, then turn key to off. Then start up as normal and see where the idle is sitting.

POST 3Original post

Maybe a vac leak deff not normal. U should also test the aos to be sure it hasnt failed.

POST 4Original post

What they said and>Smoke test once it's up to operating temp for vacuum leaks.
