it started a few days ago. my truck keeps bucking so i tried putting lucas fuel injector cleaner in my gas tank and it still does it. i also changed the oil now my check engine light is on?
the truck keeps bucking and check engine light came on on 2003 Ford Ranger
Check engine light will help you pin point A problem, but not necessarily THE problem. It's the place to start, though. Sounds like either a misfire, or an air intake issue. Start with the basics - check codes, check fuel, check air, check spark...
sorry buddy lucas isnt going to help. if u bring to me ill put it on a scanner and diagnose it no charge. brett at arctic freeze auto repair
