How many miles on your Sportage? If over 90K miles and the plug wires/coils are originals I would change them.

When you did the plugs did you notice oil on them? If yes then the valve cover gasket is leaking and could cause the misfire.


1998 Sportage - Gone.
2004 Honda Civic Coupe.
2007 Suzuki Grand Vitara - She got it.
