Did you power wash it? Oh man, you done did something messed up then. The motor can withstand a bit of road spray from driving on wet roads, since all the electrical connections have protective plastic or rubber boots, but power washing is another thing.

First thing I would do is check the battery terminals and dry them out. Then pull all the coil packs and make sure they are dry. If that doesn't fix your problem, leave it alone with the hood open for a few days with the coil packs out and hope the water dries out. After that it's time to start pulling codes.

Next time cover the alternator and distributor before washing. You definitely soaked something.

Flashing CEL is misfires. Pull the 4 wires out and look for water.

I stick an air gun down the spark plug holes to blow water out, then pull the plugs to look for damage.




IF you find this, you need to replace the plug AND the wire at the same time. Leaving one with a burn will cause the other to burn.

Pull the dist cap and look for moisture. Clean it too.

Read codes, note any that aren't misfire codes. Erase. See what comes back. Deal with it then.


Edited: Posted a 2000 under 7th gen, threw me off.

Ezone thanks a lot, i figured it was a misfire and changed the spark plugs this morning so you were right. I havent changed the wires because they were in good condition but ill probably change them too thanks guys!

Oops, sorry didn't realize you have a sixth gen, so no coil packs
