NO SPARK TO DISTRIBUTOR CAR WILL TURN OVER BUT WONT START 95 FORD PROBE
hey i have a 1999 Mazda b4000 that I drive hard. Every few weeks I have to replace #4 spark plug because it gets burnt up. I was told on GM models this is typicaly related to the egr valve being stuck open. I have not tried this yet because I can't find it. my other five plugs looked good.
