So my friends suggests I rev the engine so he can hear the exhaust. So I do so only to find that when I walked behind the car afterwards the ground was spewed upon with a black liquid. I cannot determine what the liquid is, doesn't smell like gasoline. Someone please help.

could just be carbon...

Its blowing a lot when the engine is revved up and it is very liquidy. I'll have pics of what it looked like on the ground in a second.

most likely just moisture and carbon. I have seen this from mine once or twice when i first bought it. The car sat for a while before this happened. It should go away after driving the car though.

I hope you guys are right but this is after driving it for a little bit. These pictures were taken after 2 revs to around 3-4k rpm.

I have never seen the car do this in the past and the car hasn't been washed recently and it hasn't rained so theres no outside source for the water to get into the exhaust pipes. The car would continue to spew this garbage out the more I revved it.

Carbon. Unburnt fuel. wet, could be from:

RAW fuel (though that would smell LIKE fuel, obviously)

moisture from the night air collecting in your exhaust

water/moisture in your exhaust gases (any smoking when you rev it?)

the carbon itself should be VERY light, airy, and powdery (almost so fine you can't feel it..)

You are running pig rich, my friend. I wouldnt be surprised if you haven't gotten (or will, soon) any 0420/0430 codes.

When I had a bad o2 sensor, my car did this. Just a thought

Well I replaced 2 o2 sensors within the past 200 miles so I don't think that could be a problem. I drove the car around a little more tonight it isn't spewing as much but it still is. Is there any way to fix this?

It is normal carbon. Find something else to lose sleep over.
