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.

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

POST 1 / ORIGINAL POSTEROriginal post

Drove the car home from church today with no issues. Went to run errands this afternoon and car started hard with a James Bond size puff of smoke. Ran rough for a few seconds and died. Engine sounded horrible when it was running. Replaced AOS a little more than a year ago at 93,000. Current mileage is 117,000. Oil is changed every 5,000 miles. Electronic oil gage shows three bars low (first time ever). Going to get it towed in tomorrow.

POST 2Original post

Here's to an AOS. Best of luck with this. Hope it's an easy fix.

POST 3 / ORIGINAL POSTEROriginal post

Looks like the local gas station had diesel in the super premium pumps. Of course filled up there this weekend. Would that cause the AOS to fail? Shop is pulling and cleaning whole fuel system. Looks like MAF failed too, $600 for that sensor! Talked to the station. They took my name for a claim, waiting to hear back from them.

POST 4Original post

Wow. Unheard of. An engine guy will have to chime in on what that would do.

POST 5Original post

I would think you would have misfires. Did the check engine light come on? Flashing? You need a oil change too!

POST 6 / ORIGINAL POSTEROriginal post

Definently sounded like misfires. No blinking CEL light. Oil too? Thanks for the info!

POST 7Original post

With battery out and screw on cap removed, you can see right into the tank, down to the bottom. Easy to flush and clean well.

POST 8Original post

DO NOT use electric Shop vacuum to suck gas out of tank. That would be bad!
