Check Engine light this morning

[lennyrebel]

My experience was same as already mentioned in Forum --the beast would like some higher octane fuel like a drink of hi-test. Cure all my check engine light problems, She don't like no jeep gas--cheap.

My wife got the check engine light the other day and onstar said check the gas cap. Restarted the engine and no more light. Here in N.C. we have had days in the high 20's and the next day 60. My H2 sits in a heated garage so who knows what the problem was .

One thing to keep in mind...if you don't screw your gas cap on securely it will cause your check engine light to come on as well.
