cleaned the engine bay following emay's write-up. Now when i turn on my car, it runs rough, and check engine light is on. It runs and i can drive it. it just feels rougher. Also there is a slight sulfur smell. Anyone help?

[6ER THEN I 8ER!]

did you cover the coils?

ya and the alternator with foil. We actually made some head way in the last 5 minutes reading the manual ( imagine that). Its actually the service engine soon light. I called my uncle who was a mechanic for like 25 years and he said it sounds like i was running on one less cylinder because there was moisture on them. And the sulfur smell was because raw fuel was just running straight through to the cats which then burned it up which cause the sulfur smell. So we sprayed WD-40 on the cylinders to displace the water and ill see what happens in the morning.

ok the sulfer smell is the stuff in whatever u used being burned on your exhaust manifolds... simple as that and wtf u sprayed WD-40 on ur cylinders??? well now ur definately gonna fuck shit up.

take out your spark plug wires and let them dry over night. remove ur COIL PACK and do the same. spraying it with some wd-40 wouldnt hurt



thats the coil pack now if u want to see if ur having a misfire. remove one at a time the wires to see if anything happens.

IE. remove wire 1 - engine runs worse! that wire is making a good connection.

etc etc. until you get to one that doesnt do anything. lets say u take out plug#4 and nothing happens.. well now i would check all the connections on that plug and make sure its DRY. maybe just wiping it clean and dry could do the trick.

I recommend stopping by an auto parts store and having them pull the code for you (they do it for free). Once you know the code, it's much easier to figure out a fix.

Also, I've washed my engine without covering any of the electronics before. She started right up a few minutes after and never gave me any trouble

Haha yeah, but that was unrelated I really want to start tearing down the engine so I can find out exactly what happened, but I don't want to move the car 400 miles with the engine in pieces (because I know shit will get lost lol).

Essentially thats what im doing. I sprayed WD-40 on it (instructed to do so by the mechanic) to displace the water.

Gonna start it up in the morning and if it still isnt right then taking it to the shop.
