I degreased my engine bay today, came out great i might add, however, on the drive home from my friends, i got a flashing CEL and it started running very rough, the rpm wouldn'd stay constant. To me that seems like the comp. So i looked in the air box and there was a little water in the bottom and part of the air filter was a little wet. I dryed out the air box and let the air filter dry for a while. I unplugged the battery to reset the comp. Is there anything i should be trying? Thanks. Im gonna go check and see how it works now that the comp is cleared.

I might add it only shakes and runs rough when its in gear.

I am assuming when you sprayed it off the engine was cold.
Check the distributor cap, might have water in it.
If compressed air is available I would blow out all the sensor connections like TPS, distributor, O2.

it had been cooling for about 30 min when i sprayed it so it wasn't hot but it wasn't cold. Im not super familiar with where everything is but ill find it and check it out.

No distributor on the 3.4s.

well i let it sit for a while and idle then took it up the street. Seemed to get better then the CEL came back on and it was rough idleing.

twitchee2

its almost like its miss firing or something. It idles rough, then set smooth then rough again, its fine ~2500rpm without being in gear. But it wont come down from 2000 slowly. It just drops like a rock from 2000- ~1000.

Pull the codes and see what the CEL is telling you. Probably just water in the connection of whatever the CEL is having a problem with.

How do i get the codes pulled?

SoCal4Running

You should have OBDII so you will need a code reader. Autozone will let YOU use thiers for free. You have to hook it up and everything cause they want no liabillity for your vehicle but its not that hard.

twitchee2

so if i get it to auto zone i just plug their thing in and it will spit out the code for me or is there more too it then that?

SoCal4Running

Thats it, they will hold your credit card and license while you do it. So make sure to have them.

Correct, all you have to do is take it to Autozone (they check it for free).

pull your coils and see it there water sitting ontop of your plugs

WD-40 is your friend.. I would start with the coil connectors and go from there. Just pull them off, spray WD-40 into the connector (which disperses the water) and plug it back in.

Same happened to me and i had misfire in cylinder 4, it somehow managed to foul all of the spark plugs/ wires.

twitchee2

just replaced the wires and plugs?

jwbehm

Thats what I did and it was 100% better.

I degreased my Runner's engine today also, but I put grocery bags on alternator, K&n, and a few electrical parts to make sure I didin't get water anywhere...she's just smokin' a bit after I let er run to dry off..Is this normal burn off?? sorry to hi-jack just curious--it smells like degreaser!

Im going to try and get it to auto zone tomorrow. Its not what i would call safe to drive though.
