I had a 97 Explorer XLT, I changed the plugs to a Bosch twin fire type, and
it caused my motor to mis-fire, the computer did not like the plugs. It
caused my engine to show a "check engine" Light on the dash. I think it is
funny how other brands make a plug for the Explorer but you can not use
I whet to the dealer and they changed out the plugs for over $100, I can
not believe it. I think the computer has something to do with it.
