Read evidence and context

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 performed work without a confirmed outcome: 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.

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

POST 1 / ORIGINAL POSTEROriginal post

I had this scary failure for two months and would like to share the information with members suffering from random stalls at signal stops. 1. Random stalls at signal stop. 1-2 times a day , without CEL ! 2.Longer cranking (4-5secons ) followed by faster idling as 900-1000rpm....(camshaft and crankshaft sensors might help each other.) 3.Rev’ed and idled fine other than the stalls and faster idling 4.Cleaned the throttle valve and replaced MAF , no success. 5. Went to a shop , then he found ‘ Engine RPM ‘ left in the TEXA scanner 6.Finally almost dead at the shop and replaced the crankshaft speed sensor. 7.Solved , and I learned that the other sensors might be dead soon or later. 8.Camshaft , Knock , Throttle sensors ordered to minimize the budget. If helps any.

POST 2Original post

Thanks for your info Yukio. The crankshaft speed sensor is not an uncommon issue and usually fails when warm. enjoy & kind regards Andy

POST 3 / ORIGINAL POSTEROriginal post

Yes, but I was not thinking that the symptoms were from the sensor. No CEL and rev’ed anyway.??
