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?
