Well, shampooed my engine to clean it up for the summer time, used my pressure washer (not on hard core blast type setting) and sprayed here out. ( +used a citrus based cleaner to keep the enviroment clean). I fisnish, let it dry for a bit, go to start her up and I get this putt putt noise coming out of the exaust, and at first the engine was shaking violently in its place....

Well, I let it run for a little bit, and the shaking died down a bit, but the exaust was still sounding as it is was putt putting itself. The engine has not stalled out or anything. The engine sounds fine, while when I rev it..I get this sound from the exasut like it it bogged down or something... odd..

-I checked all the sensors i could find, all were snug and tight, and not wet.
-IDI cover was bolted down tight in place, so nothing could have leaked onto the spark plugs.
-Air filter is bone try, checked the throttle body and it to is bone dry.
-I have rinsed the engine down plenty of times before.. Never Have I had an issue.

**MY only idea, is that when I was washing, water could have seaped down threw my new flex joint (off the header to the down pipe) and maybe seaped down into the cat.. Although I do not beleive that is the problem...

Sounds like water got into the spark ingnition system somewhere, grounding the spark. Cat bogged down could be unburned fuel. If it keeps clearing up at the same rate, you should be OK soon. Running a cat-cleaner may be a good idea to avoid a clogged cat. Don't run it through the gas tank, slowly pour it down the throttle body while making a FAST idle.

Hold on pour it down the TB. I dont know what year his car is but I doubt it is TBI. All cars nowadays are EFI. If he poured anything in hs tB it would go in the intake.

Sounds like your putt sound is a misfire. You got water on a secondary ignition component and it got wet. Sometimes they have to be replaced to fix the problem. Spark plugs, wires, coil, ICM none of them like water.

Its weird though, the coil pack is down tight, there is no way water could have gotten on it . I sprayed down beneath the cover on the opposite side of the IDI cover..... cleaned a ton of grease buildup out...... I hope it drys out and is fine....

Took her for a big rip, she is great now, working like a charm.

Next time you should coat all the electrical parts good with WD40. If you didn't know the WD stands for water displacement. Works really good inside the cap and pug boots on on older cars.
