Sorry if this is a repeat but did not show me i had posted this from last night? 2000 C2 So I randomly get these codes P0507 idle control at stop P0466 stop valve, activated charcoal P1130 oxygen sensing adaptation bank 2 I Will start the car sometimes and they appear or if I really get on it and rev it up they will show up. And then normal driving after a few starts they will just disappear again. Runs and drives great i think but maybe not as good as it could be because of a vacuum leak or something?? I will say this car can idle high at times but then come back down. And usually only happens when. Its hot as it seems to run a little hot in town like needle not quite at the 3 rd notch on temp gauge but close. When normal operating Temps it does not do it as much but does sometimes. These have something to do with each other or they are completely unrelated

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.
