I believe the water on top of your spark plugs was the problem. Hopefully you had your dizzy, alt.,and if you have an aftermarket intake you had that tied off with a plastic bag and zipties. You could spray water under your spark plug boot (grommets ) with that high pressure water. See how well the car runs for a day or two, putting oil in your cylinders I don't think you'll have to do that if the car still runs fine but, you can to put your mind at ease I don't think it will hurt it.

 

why do you need to put oil in the cilinder? the only time that I know you do that is if yore going to check the compresion.

You propably got water in the wires causing the misfire, and some water being sucked into the intake is also possible.

Read up on Hydro Lock - That basicly what could of happened. Id drain the oil and do whatever ppl in that situation do. (I belive remove the sparkplugs and cracnk it to make sure theres no water in the cylinders.) But you should be good to go now. Getting water on the sparkplug wires like that is a common proplem and nothing to worry about if thats all that happened.

 

Also how did the corroded plugs look? wet, carbon between the diodes, yellowish,oily, etc.?

 

Plug #1 was a little wet, like a few drops of water on it. The other 3 plugs were bone dry.

Here are pics of all 4 plugs.....



I'm pretty sure plug #1 is the dirty looking one on the right in the pic below.

 

That looks like pretty much normal combustion deposits on the plugs, how many miles since the last plug change.

I think you just got a little water around the plug wire boots which caused your misfire, then got paranoid.

I think everything will be all right now that you have fixed the problem.

 

It's been about 21k miles since the plugs were last changed, so these NGK's in the pic are 21k mi old.

Yes, the car drove and sounded perfectly normal when I drove the 5 blocks from Autozone back to my apt.

Do you think any damage can be done to the motor by driving it for 40 miles while it was misfiring earlier today?

 

yo drag relax man all you did was have some water get down your plug holes all you got to do is pull plug wires off and dry them off real good if you have carb spray use that and let them dry a few minutes ..
i have seen it happen many times 87-89 integras are the worse to get water in plug holes after washing engine ,,,anyho after you dry it all up, clear the code and you are fine

 

I agree, those plugs look to be in normal condition after being used for a while. I think your engine bay cleaning may have permitted water to penetrate your wires. Often when you get cylinder misfires the first and cheapest step is to do a tune up. It solves the problem about 95% of the time. Now why this problem didn't occur right after you washed your engine bay is a mystery to me.

 

yeah i did the same ****...lol I actually noticed the car stuttering and when I removed the plug wires the entire plug well was full of water. I took a sprayer from a bottle of windex and stuck it in the plug well to remove as much water as possible. changed plugs, wires, and seafoam in the gas tank and oil. changed oil 2 days later. evrything is cool now. that was like 2 years ago. I hate washing my engine bay!

 

Plugs don't look bad. The two lower ones look to be running hotter than the top two but those are good looking plugs. yes you can damage your car driving it while it's misfiring the combustion chambers are having all sorts of he!! happening inside of there, not the proper spark at the right time and the engine could be hurting very badly. Since the car is running fine right now just watch it and be careful with the water it's good for outside the engine to quickly clean it but, you get it inside and ouch!

 

I think your ok. Take off the oil cap, and check the color of the head. If you did serious damage, youd know though. Since you were misfiring, Id reccomend a oil change, just to be on the safe side. Check all your vacuum lines, since water coulda gotten in there. ALso check your air filter, see if its wet, hehe.

 

You'll be fine.. my car has been running like **** for over 2 years!

I'm very familiar with those codes

 

You got water on top of the spark plugs... i.e. under the spark plug wires. Not in the engine.

I've done this before on one of my cars and that's exactly how it acts. Your car is fine.... it just causes misfiring and does not hurt anything.

Some dumb *** that drove his freshly rebuilt supra engine home the previous week did the same thing. Thought "Oh I should spray down the engine." ALL the plugs where full of water. Car would not run. He was like It was working fine cause I drove it in, then it wouldnt start!!


Moral: Its good to wash your engine, just be cautious of the plugs/cap/ electronics.

Why are you all freaking out and chainging oil and plugs and ****?
Just leave the wires off and let it dry or better yet blow it out with some compressed air.
