I'd check to see if the gas cap is tightend all the way. Seems that is a common occurence for CEL's to come on.

are you sure about that...
The only fuels that are offered in most states except for western states are
94, 93, 89, 87 octanes.

I've seen a gas station around here that has 94,93,92,91,90,89,88,87............it was great cause most people don't know what to put in when they see that many choices

i actually came across 91 and 92 octane today it was kinda weird, i needed gas badly and was the only place near by. draw backs of NH. put 2 gallons in to get me where i was going, didn't want to run out of gas in the snow. my suggestion though is don't fill a tank with 91, splash some in there but get to a pump with 93 quickly you might be able to reverse this curse you have by putting some octane booster in there

These cars are awesome, but be ready to pay the big bills that come along with them, they are "Nice peices of sh*t" as my friend says

i see 91 and 92 all the time... different "chains" market different octane levels - even if they get it from the same distributor... they just put their specific additives in them and slap a sticker on the pump.
