I was going to but I let my buddy borrow the car for tomorrow so he can look at it while i'm at work, but all my stuff to test that crap were at work so i couldn't do it tonight.

And zero i would suggest not to wash anything with water. i used a low pressure water hose as well and now all this. fml.

I ran into the same problem when I tried to clean the engine, but once it dried the next day it ran fine. Not much help now but in the future put a cloth around each plug and no problems. If your still having problems it might be worth removing the plugs too.

it was bank1 sensor1 o2 sensor. The only reason i can explain why it went bad was because it was my heater core to intake hose that was leaking and when i pulled it off to replace it coolant leaked all down on the exhaust, so that might of got in there and effed it up some how. but i'm very happy it's running good again lol.

im confused how the coolant ruined the o2 sensor isnt it hermetically sealed? the reason i ask is i have a 02 gt and the coolant hose from the back of the intake manifold to the firewall was leaking, i fixed it now im having problems, it idles fine for now but under load it jerks like crazy and has no power....any ideas?
