engine service light on after 300 miles

Regarding the loose gas cap, I heard an interview with a car shop owner last week. He said that almost 2/3 of the "check engine" lights that come into his shop are related to the emissions system. In particular, almost 1/3 are loose gas caps. It appears that there is a vapor recovery system attached to the gas tank (and the tank is under very slight pressure). Well, when the gas cap is loose, the vapor recovery system can't function properly (hence the "check engine" light). Long explanation for one of the likely causes. I am not a mechanic so my explanation may be slightly off. I still find it amusing. You should be able to tighten the cap, and it will go off soon thereafter.

YAH WHATS UP WITH THAT! your keeping me from my 12 pages of math work due in 8hrs lol, i meant this board hehe im either in the car, at school, on the computer for bmw/m3 stuff, or doin homework, guess what has priority over everything? take a guess eheh m3 stuff, guess i better get to the math work though so i can get the m3 thats on order for june delivery ;-) i hope my m3 wont take me away from my homework or my dad says my m3 will go bye bye but yah i would take it in cause its free heeh, so just get it over and done with so no further dammage if it can happen can be done
