Fuel injector question

Can a dirty or intermitant working fuel injector cause your engine to backfire through the exhaust?[img]/phpBB/images/smiles/icon_confused.gif[/img]

well...lets say that a very lean cylinder can cause a "pop"..but usually that's at a higher rpm with a load on the engine.. if it does it idling or at part throttle i would look at maybe something different. maybe bad plug/wire? more info might help??? good luck, ron

It does it at part throttle light load, usually when the engine is cold but it does it when hot too.

thanks
