My check engine light came on my 1996 Mustang GT?
I was on my way to Walmart and it came on randomly. It drives just a fine as it did before it turned on. No unusual ideling, no smoking and it's not missing. Could it just be a simple sensor? I know this is a dumbass question but I can't help but worry. I've always had bad luck when CEL's came on. It runs like a brand new car, just has a damn light on..
