I replaced the fuel pump/filter, and all the plugs. When engaged in to drive or reverse it sputters. Also has a hiccup while driving. Used injection cleaner. No help. What can problem be?
Is the check engine light on? I take it you have a gasoline engine? If so you may have a coil going bad. Eventually it will code and you will know which one is bad.
Yes it is gas. Check engine did come on. Code read misfire but didn't say which coil was bad. Cleared out check engine light. Just wait to come on again?
