Contour Enthusiasts Group Archives Forums Branches Capitol CEG Hope I can fix it

I was having a little light throttle stumble that started about a month ago. I washed the motor today and I used as little water as possible. But now I have a BIG stumble. I drove around for quite a while and it seemed to get a little better. The car has just under 80k and I haven 't replaced the 02 sensor yet, I'm thinking about doing it tomorrow. If the plugs got wet no big deal but does anyone have any thoughts?

My guess is you are mis-firing due to the water in the plugs.

Yeah I was thinking that too. There is that little valley on the cylinder heads of zetecs that LOVES to trap water and gunk.

Yep. I hate that thing.

mine does it all the time, but somehow i never misfire!! its almost always has water and gunk in it, but i dont know how it gets in there, cause the plug wires are supposed to seal it!!
