My motor pings after engine cleaning. Why?

[EIGHTEIGHT_GT]

Since I simple greened the engine compartment I cannot floor my car without it pinging. I even tried using premium. The day I cleaned it I was hesitating and having problems missing for a few days because of me apparently getting water some where i shouldn't ( even though I was careful). Ever since then my car does feel like it is a little low on power. I mean I am due for a tune-up but I dont think that is the problem. Any thoughts would be appreciated.

did you get some water on the individual coils on the each plug?

Chg the plugs...after removing the COPs, use compressed air to cleanout each spark plug 'bore'. Also used compressed air to clean and dry out each COP. Here's a great write-up on plug changing.

I agree with the above posts. Just in case though check your intake for water and check the oil level (just in case). Don't drive it around until you find the problem.
You can tell where the pinging is coming from by getting a long screw driver and placing your ear to the handle end and moving the other end around on your engine.

Fixed the problem. I changed the plugs and whatever I did seemed to work. There IS a lot of crap that gets down in those holes. A small piece of dead pine needle accidentally went into the hole and I freaked... until I realized that it would just burn up. I ripped one of my spark plug boots too. Be careful when pulling the boots off the plug if you dont know already. Just FYI.
