I have a 97 F350 4x4 with 70000 mile on it. Recently the check engine light has come on and has remained on. Does anyone have any idea where the problem may be? Is this something I can fix or do I need to take it in? Do you think it is covered under the 100000 mile warrenty?

 

Without a code who knows.

 

the warranty is 5 years/100,000 miles, so no
take the truck to an "autzone" or "checker auto parts" they will usally scan it for free and let you know what the codes are. once you have that info we can better help you
