Great news everyone, I cleaned my engine last night and it looked great! I let it dry for 6 hours with the hood open and then turned it on. It was idling kind of rough so I turned it off and then let it sit overnight. next morning on the way to work, the car was running like total crap. The engine was shaking like crazy. I had to get to work so I turned it off and walked(I was an hour and a half late) When I got home I popped the hood and took a look. After listening around and feeling around I came to the conclusion that one of the cylinders just wasnt firing. I turned it off and checked the front three plugs(its the 2.7L) They were all coroded on the grounding sides. I figured no big deal I'll just clean them off and try it again. No good, it ran a little better but you could still hear it misfiring. I decided that maybe driving it might change it. I put it in reverse and when I let the clutch out it made this horrible grinding metal noise as the engine was put under some strain. almost like the sound of a rod smaking the inside of the cylinder walls. (just awsome) so here I am waiting for the dealership to open tomorrow to go spend a few thousand dollars probably to get it fixed. If you guys think its a good idea to clean your engine, think again. I used the DIY here and followed it step by step and now I probably just screwed up something real bad. I covered the filter, the coil packs, and the belts. I didnt even use a pressure washer to clean it, just water from the hose. anyway, I'm done venting, at least when I get the car back it will have a bunch of new **** on it =)

I use gunk's engine cleaner and have no problems. I cover everything I think will cause problems and make sure the plug boots are seated good and then Im careful where I spray the water. It can be done safely, you just cant throw the hose in the engine compartment and pray it doesnt spray where you dont want it to.

I think it was just coincidence that you had problems with your engine after the cleaning. I cleaned mine according to the DIY and my car has been running fine since. I didn't bother to cover anything, but I also used a light spray with the water.

I tried cleaning it before with simple green and that didnt do anything for it, there was still stains on the upper plenum so then I tried the engine brite for newer engines, nada, then I tried the DIY post. Thats when the **** hit the fan.snyper1ad said:
