Water...ohhh water. Need some help here

So Pensacola had about 22 inches of rain in 12 hours and making it home from work the roads were mostly flooded. I made it home but the truck was running sluggish. This morning it gave me a misfire code. p0300 and p0302. I pulled the cap off of number 2 cylinder and there was some water under it....so what do I do? I have a 2002 toyota tacoma 3.4L V-6.

 

The cap...you mean sparkplug? Is the oil milky?

 

I think he means the coil pack... ?

I'd say before you start replacing things, unplug all the connections, let them dry (maybe hit them with some WD-40 to speed it up?), plug them back in, and see how it runs.

 

Hit all the connections with some wire dryer.

To clear things up..there is a little water sitting atop the spark plug. By cap I mean the plug wire. I sprayed some wd-40 to see if it will help dry it up quicker. I wish I had something to blow the water out but I do not.

 

Thats a good idea...luckily my neighbor had a compressor and blew all the water out. She runs like normal now. Any problems I should watch out for later on though?

 

Had this happen on other vehicles. Water floods the spark plug shorting out the COP.

Blow it out with anything you have available, canned air, air compressor or hair dryer. Once completely dry, put some dielectric grease in the COP boot and reinstall.

22" is alot of rain and driving through puddles throwing that water in the engine compartment doesn't help. The COP boots are suppose to seal out water but they dry out, shrink and crack with time. Don't replace any COP's just yet. See if the dielectric grease works first.

 

You should check out the rest of the plugs too. If you can't find compressed air or anything at all to get rid of the water, just pull the spark plug and turn the engine over with the starter motor to blow the water out. Same thing you'd do if you sucked water in the intake.

 

Don't pull the plugs and risk hydrolocking the engine. If you absolutely have no way to blow out the air, fold paper tower or shop towels and push them down around the the spark plugs to soak up the water.

Edit: I should add that C2C is correct that you should pull the rest of the COPs and make sure everything is dry.

 

Thanks guys!

 

You won't hydrolock the engine with the spark plug out. LEAVE IT OUT being key. Also pull all the spark plug caps off you do not want to fire up.

Better yet forget everything I said, take it to your mechanic and let him worry about it.
