I'm so mad right now
I had a guy detail my Ex yesterday, and in doing so he washed the engine and sprayed some kind of shiney stuff all over. It looks really good, but now I have a misfire (i think) occuring. It could be from the water he used to clean it, or from the stuff he sprayed on it. I think my first step is going to be to try and get the stuff off of the engine. Soap and water should do it. I'll take my air compressor's blow gun and dry it off as best I can, making sure to get all of the water out of the spark plug wells. I can use my NGS to look at the misfire counters and see if the OBD system is picking any of this up. I'll take if for a drive on the e-way as well to get it nice and hot to try an burn anything off that may be causing this too. Damm!!! as soon as I saw what he did, I knew this was going to happen. If I have to take it to the dealer, he is going to pay my $50 ESP deductable for sure!!!

Most likely the shiney stuff is Armor All. Some detailers will use a pure silicone spray as well. There is a product called Super Clean that comes concentrated. To remove the " shiney stuff " I would dilute it 50/50. that should do it. I have detailed cars for many years.. ( not so much lately ) and luckily never left a car in that condition, I always drove it. I did however almost kill my own van. Water got in the cam shaft position sensor connector and kept killing the engine after so many minutes.. arghh that was a tough one to debug.. HTH

When I first got my 2000 X at 68,000 miles I pressure washed the engine compartment. Like you, I then had a misfire and it turned out to be one of the coils had failed. Expensive mistake. The owners manual actually cautions against washing the engine.

Well, the miss went away fairly quickly once I got the engine really hot and drove it on the e-way for a while. I suspect that it was nothing more that some water down in the spark plug well(s). Still, I was pretty pissed yesterday.

Actually, I am sure the problem will come back what happens is water passes through the seal of the coil. and goes down the spark plug well. Driving and getting the engine hot, wont cure it. It will cause the water to evaporate, but it will re form causing the mis fire. The BEST thing is to remove the coils and let the dry for a little while and re-install them. You will see the water droplets on the rubber of the coil leg.

You're both right. First time for me I was rollin thru a small river too fast and got water inside enough to cause the misfire issue. When I got home I blew them off. Didn't help. I took the one offender out to dry (caught using my SC tuner to diagnose ). It was more than a week before I was able to fix it.
The second time I was a few hundred miles from home, about 50 miles from nowhere playing in mud when I did it again. This time I just drove it home. By the time I got home the next day after all the freeway miles, it was all good. Dried itself out.
