Moisture on Plugs!!! - Honda Prelude Forum

SolRayz · 03-23-2004, 02:48 PM

Well my H23 has been acting real sh!ty for the last week and it seems like its getting worse. When hitting the gas the car seems to bog down down at lower RPM's and will stall out at times. Feels like low compression. I checked the the plugs and noticed some water droplets on the the plugs and plug wire shafts. I also noticed some steam coming out of my intake? Where could this water be coming from? I havent been through any puddles so that couldnt be it. I was thinking maybe a blown head gasket but I checked the radiator and it is full with know sign of gasoline. Please help!

I don't think the water is related to your problem. I think the water just came from rain, or washing the car, or pretty much anything else. If there was water in your cylinder, you would have blown a piston, or it would have just evaporated. If you were leaking coolant from the head gasket and burning it, you would see lots of white smoke. When troublshooting these types of problems, it is always important to remember that combustion requires fuel, air and spark. First check all of your ignition components (wires, plugs, distributor, coil). next, check your fuel (clogged injectors, injector resistor, fuel pressure, water in the fuel) and finally (and least likely) check your air supply. Check to see if your computer is throwing any codes. If it is not, then you can rule out the problems that would throw codes. Again, I do think that the water you found is coincidental.

Well, there was no white smoke, my plugs are fairly new NGK coppers, my plug wires are fairly new NGK's, I havent had time to check the distributor and coil or any of the fuel components. But it still strikes me as odd that water would find its way to the plugs! How can that water get there!?

Something else I need to add. This all started to happen after filling up at a local gas station last week. Not to blame it on bad gas, but that what I thought it was and didnt really think much about it.

Well, to go back to the water in the plug, I don't see how it could have possibly gotten there via the cylinder. It must have somehow gotten around the plug wire and into the cavity where the spark plug sits. I have a feeling that this water that was sitting there found it's way onto the plug as you were pulling it out. Does this seem within the realm of possibility? I just don't see how a spark plug (if it is igniting and there is combustion occuring in the cylinder) could possibly have any moisture on it. As to how you could have possibly gotten water in there, it's impossible for me to say. I would get rid of all the water in there, and see if it happens again. But again, I still feel that the water problem is completely unrelated to the hesitation/ bogging problem. Bad gas could indeed be the culprit. Good luck.

Hey trident thanks for the help!. I really hope it turns out to be bad gas, if thats possible!
