Leading evidence: 'o2 sensor also' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'o2 sensor also' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Fill fuel and gas cap not properly secured' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Other common cause is bad O2 sensors, I've had mine replaced twice.

Most commonly occurs after filling fuel and gas cap not properly secured.

I know for a while they were replacing the filler cap gaskets.
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.

Have made my way 250 miles from home for that Christmas visit. After encountering several accidents that slowed and finally stopped my progress, the chech engine light has come on. The light came on after a lot of stop and go, engine turned off after a substanitally quick run and then restarted after 20 Min. It showed itself after a particlarly annoying encounter with slower traffic from which I escaped by use of the throttle.
No one is around at any dealership to download the fault. My dealer provided his opinion that the yellow check engine light means the car can be driven but needs attention soon and the owner's manual seems to agree. It has normal power and everything as it normally is except for the light. I am thinking of driving it very little while here, doing the 250 mi back home and turning it into the dealer to check. 99 C2. Thoughts anyone?
The "check engine light" indicates a fault in the emmission control system. Most commonly occurs after filling fuel and gas cap not properly secured. I know for a while they were replacing the filler cap gaskets. Other common cause is bad O2 sensors, I've had mine replaced twice. Probably nothing major, often times will reset itself after a series of normal startups. If all other indicators are normal I would not worry too much and get it checked out when you get back home.

Also can come on if oil fill cap not correctly seated. I would drive the car for a few days- if the fault corrected itself, the light goes off after a few start/drive/shut -off cycles.
Thanks for the relpies. Your comments mirror what I had found out talking with some friends. I am thinking O2 sensor, since it sat idle for 20 min, then in stop and go for another 20. I will try both the oil and gas cap and have a good look around. Thanks again and Merry Christmas
