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.

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

  • Rennlist: 1 discussions

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

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

POST 1 / ORIGINAL POSTEROriginal post

I washed the car this afternoon and went for a short ride because it's the first nice warm sunny day in a while ... and about 10 blocks away, my engine stumbled at low speed after leaving a stoplight. I went around town and out on the highway trying a range of speeds and revs but the problem did not resurface. Could this just be from washing the car? What could get wet that would cause a hickup like that? Or is it possibly the start of some other problem? Ideas?

POST 4 / ORIGINAL POSTEROriginal post

Thanks guys. Is it common practice to replace them all at the same time? The car has 75,000 miles.
