First my check engine light went on. After checking the oil I saw it was getting low, refilled it. I took it to jiffy lube cause it was time for all that. Then, a few days later, the light came on again. I'm going to take it to a repair shop, but I want to know what to expect. [more inside]

The check engine light in my car is cycling on and off (on for a week, off for a week). Two questions: 1. If I take the car in for an emissions/smog test when the check engine light is off, will it pass. 2. If it fails, and it is early enough in the month, will I be able to drive the car until the end of the month when the sticker expires, or will it be "red-tagged" as soon as it fails? [more inside]
