1991 Ford Ranger "engine light"

Kelster · 05-06-2008, 12:08 PM

I have a 1991 Ranger the "check engine light" stays on and has been for months now, nothing that I know of is wrong, truck is acting fine. do I ask for a diagnostic on the truck to find out what is causing it or how do you determine whats causing it. I have to get my truck smog cert. soon will the smog place pass it with that light on? Any comments would be helpful thank you.
