Take the car to Autozone and see what the light is for. Water should come out of your exhaust after combustion though. It's normal. It probably is just mixed with some carbon in your exhaust and coming out black. Next time you're on the highway, just look at a car in front of you and watch their exhaust. It will drip.

You should have a logger with all of your mods. And the logger will tell you the CEL code.

MAF was not connected for some reason ?( check engine light stil on tho

Condensation...

The Catylitic Converter changes exhaust into many things...including H2O (water). Do some research on them and you will see that this is normal. Another reason could be that it rained or you washed your car and some water got in the exhaust, and the reason its black is because..Its exhaust of course. Also, only thing you can do to see why the light is on is from a logger. So go.

That;'s probably why, if you didnt have a CE light before, of course we shouldnt assume, the CE light might be something else, but because of your statement, this might be the obvious.

Since you plugged it in and it is sitll on, reset the ECU, see if it comes back on. Mine came on because I didnt have the mas plugged in, and even when I did the CE light for it was still on, how I knew it wasfor that, I have DSMLink to check, I reset the ECU, CE light gone, and did not come on again, try that.

How would i reset? unplug the negative wire from the batery then plug back in?

I'm not sure if that works for OBDII. I would just go to Autozone. They can clear the code off for you, and read it in case it wasn't the MAF.

thats how i do it i leave it unplugged over night, but you probably only need to do it for like 15- 20 minutes. And the water probably is condensation, does it only do it right when you start the car up because it can be low combustion chamber temps and like what was posted above the cat could be making it come up like a liquid but if its not spraying out and constantly doing it I dont think its anything to worry about.
