Car Misfiring - water + spark plugs?

Hi,


I have a 2003 tiburon that is supercharged (water cooled) with a cai.


I was driving yesterday in a pretty bad rainstorm and about 2 minutes from home, my car started to misfire. Got it home, read the code and it said there was a problem with cylinder 4.


Took that boot out and there is a little water in there, checked # 2 and there is a little in that one too. Number 6 had a lot of water in it. I dried it all out and everything seems fine now. I have new (1 step colder) spark plugs to put in it, im just wondering what could of caused this? I have a c/f hood and unfortunately one of the vent seems to dump the rain right on the boots, but shouldn't they stop the water? They were sealed (little pop).








Also what would cause corrusion in there? I know i'm running rich right now, but I'm getting re-tuned in a month.








thanks in advance.

I think you answered your own question. Maybe that paticular spark plug did not crush its sealing ring quite enough and allowed water to intrude. reinstall spark plugs and ddcheck the tourqe.


If you havnt changed the plugs you could always use the garden hose to see if you could reproduce the problem.


If you are talking about corrosion on your plug itself, it happens. Depending on grade of plug. should also only be on the wrench area. Anywhere on the sorrounding engine block is a concern.
Reply:you may try spraying the wires with spray silicon. this will help to repel the water so it will not soak in the rubber. what you are experiencing is what we in the south call "drowning out a vehicle". we play in water and mud a lot down here and experience this a lot but if you spray the silicon on the electrical system we find it works well.
Reply:the leak is probably the problem with it,if there s no anti freeze missing from it,and that was all it was ,id say you,ll be ok on it,and the hotter plugs might help it a little,the tune up will probably take care of the rich running problem in it,good luck with it.,,PS its probably going to do this every time it rains though until you get the leak fixed on it.
Reply:Its possible that the water might have seeped in past your injector o-rings. Or like you said the spark boots. You are going to have to fabricate something to keep water out of that area. The corrosion is most likely due to the water.
Reply:no it is not stopping the rain. it is just like vw problem where water gets in the airtube near the innner cooler...... what i would do is find away to really make it water proof
