umm prolly varies but takes my car about 5-6 miles. used to take about 10-15 miles but now it comes on at around 5. but prolly varies depending on what problem you have.

All depends on the problem...I mean, it can take a few days at times. I had that once, the upshift delay problem...I reset the CEL by the battery method, didn't come back on after driving for a while. But a few days later, it came back, so it all depends on when the problem decides to throw a code again.

did you read the code that caused the cel to come on?
I have a CEL once a week now... P0400 the EGR valve low flow.... have been resetting it with the scan tool for past 4 weeks.... knowing what the cose is about is very important especially if you get a repeat code...

yeah mine is that p0505 error, idle air control malfunction, im gonna try cleaning more of the throttle body today. Is this a good way to clean it by starting the car and spraying some into the body so it cleans it better and probably cleans more of the oxy sensor as well?
