Question about 1998 Ford Explorer
To start this truck has 199,000 + on the engine..it reciently started missfiring spark plugs. I've replaced the plugs 2 times now and the wires once. I just put a new coil back on the drivers side and it ran fine for 2 days and is miss firing again.. A friend checked to see how it was firing and some of the wires had good spark n some had barley any...Do u have any idea what could be causing this???
You might want to replae the map sensor and or the egr valve either of them can make it backfire
