I took my 98 base w/65k miles to get an oil change yesterday at a Jiffy Lube and later on that day my check engine light comes on. Coincidence...I don't know. I've had all my regular service done at the dealership and just decided to get an in between oil change and the check engine light never came on b4 other than at startup. I spoke to the guy at the place and he says there's nothing they could have done to cause that. The car does have oil in it but I was wondering if there was any mistake they could have made to cause this. Any ideas? Thanks.
