I must agree with the above two posts. If it is a fuel evap issue (99 out of 100 this means gas cap) then I would take it into the dealer and have them replace the gas cap IF you haven't gotten gas since the last time this came on. It could be that you have a defective cap. Usually though this light comes on after you get gas...

HOWEVER...do not ASSUME it's the gas cap. Call OnStar and find out for certain.

My check engine light came on a few weeks back. took her in and they found carbon build up in the catylitac converter. They replaced it and she good as new.:thumbs: If I'm not mistaken, I've read a couple of other threads in the past where other Sky's had the same problem. Until they run a diagnostic test on it you'll never know for sure. Good Luck.:thumbs:

gas cap reset can take several days to kick in.

do NOT fill tank past check point (no top up) and three clicks on the cap to tighten

happened once in the beginning on my SOL...nothing since...'cause I tighten the cap three clicks

I just picked up my Redline from the service department, they said there were five listed errors all related to misfire. They called the main service tech at Saturn/GM and was told the problem was probably due to moisture in the cooler system typically caused by the weather. They cleaned it out and checked all the electrical connections tied to it, then they reset the engine light and test drove it about thirty miles. The problem seemed to be fixed but they did say that because they could not see how the moisture had made it's way into the system, that it could happen again, but it wasn't anything to worry about since it did not affect the performance.

Personally, every time I would go to Citgo or 7-eleven I would get a check engine light on. I stopped going there and have rarely seen the problem. Watch the gas stations you go to. My observation is that most misfires are caused by poor fuel or excessive moisture in the gas. Oxygenated fuels contain ethanol. Ethanol attracts water vapor and you end up with water in your fuel tank. Ethanol in your fuel is purely political. Poor fuel economy, lousy horsepower and they charge more more it when it cost the gas stations less. By the way, for those of you purchasing premium fuels, shady gas stations boost the octane numbers by increasing the ethanol content. You end up with higher octane, more water in your tank, poor fuel economy, poor performance and the occasional check engine light. :banghead:

Sorry, just my $.02 worth.

I recently got a check engine light. Onstar said it could be either a O2 sensor or cat. The dealer replaced the sensor first, then after the light came back on they replaced the cat. all is good since.
