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.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

40th anniversary 996. Above around 80 mph, if I let off the gas, especially abruptly, the PSM starts blinking and if I grab the brakes I can feel that the PSM is activating them. More so in lower gears. Thing is, the car isn't losing traction at all. I drove from Jacksonville, FL to Lexington KY and back and to get around the problem, which started in SC on the first day of the trip, I just disabled PSM. I even drove in the rain at...expeditious speeds...in the mountains with no real stability issue. I don't run stock tire sizes; I run 245 and 285 MPSS tires. I ran the exact same tires for 3 years with no issues. I replaced the very bald rears with new ones just before the trip. The fronts have lots of tread left. Only thing I can figure is that the difference in wear between the front and rear tires is enough to trip the PSM at higher speeds, since there is a rotational difference in the front and rear wheels? I hooked up my durametric and there are no faults in the car whatsoever.

This is a source reference. Confirm exact model applicability in the original material.
