I have a 1996 Ford Windstar 3.8.Ck engine light on. Scanner shows P0302, misfire on #2. I replaced the spark plug & wire on #2 but after driving light comes on again. What should I look for? Thanks

Recheck and see if it is the same code..could also be a fuel problem causing it....like a bad injector...When was the last time the fuel filter was changed?.....did you run out of gas?....Jim

Yes it is always the same code. Have never run out of gas. Fuel filter serviced about 3 months ago. The trk seems to run fine except very slight hesitation at off idle. Trying to get trk ready to pass Tx state emissions test.

Unplug egr valve and see if it still sets code.
Is the miss at idle or when you speed the engine up.
If only when you speed up the engine and it does not do it with egr valve unplugged.
Check the EGR valve ports in the intake?

How many miles on it.
Good hot spark to no 2 plug?
