We suddenly lost acceleration while going uphill, it sounds bogged down. while driving on flat land the problem is intermittent, however while trying to go uphill it has very little power. We have changed the plugs/boots, the plastic casing and the fuel filter as well as added fuel injector cleaner and moisture removal. Is it possible one or both of the coils are bad? If so how do we check to see if they are bad? If not what can this be? Please let me know all the options. We are stuck in Washington and need to get back to Tennessee. Thank You!
