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.

Driving my C4s this morning and at about 4000 rpm car starts missing and ABS-PSM warning comes on. Shut car off and restart and warning lights go out but at 4k rpm car misses and they come back on, any ideas? Runs smooth until then.
MAF sensor....try cleaning it with CRC mass air flow sensor
Thanks! That was my guess but was not sure with the warnings. Also another quick question, when I park my car with wet brake disc the calipers seem to lock on the disc, this morning it was worse than normal and really had to rev hard to brak lose, is this common? doesnt happen on any other car with disc.

This is from rust forming on the rotors. It will happen every time you wash the car unless you take it out and drive it after you finish washing it.
Dry your brakes before parking. You can dry them by lightly appling the brakes then step on the gas and drag the brakes against the engine in a low gear for a short time - 15 seconds or so. Note, you need to apply the brakes then the gas in that order else the engine goes back to idle if you apply the brakes while your foot is on the gas.
