CEL in 99si
120k on the car
all maint is always done regularly.
oil changes..spark plugs..wires...etc
the car has always had a rough idle and i heard about lucas gas treatment and i put about half of one of the big bottles
the car runs great
i also have been mixing the gas i put in like sometimes ill put in a lower grade and sometimes higher..premium is nearly 4 dollars a gallon here
so anyway i was driving last night and my cel came on
car still feels fine starts right up
was this caused by all the mixing of fuel that i have done and even possibly the fuel treatment?
thanks.
also my gas cap is not loose haha

The first step in diagnosing why the check engine light came on would be to retrieve the code...
