black exhaust... usual problems?
94 f150 5.8L
Now I was wondering what might be causing this. When I start my engine, I have to give it a little gas, and it's fuel injected. is this bad?
I have dual exhaust exiting the rear. There's two spots beneth the tailpipes that's speckled black. It's because I get black moisture building up inside of it.
The exhaust is a much darker color than it used to be. Something has changed, but I can't notice it. It smells different; more pungent.
Are there any normal things that could cause this that are common? Any questions, feel free to ask. This doesn't seem healthy for my engine...

It's running rich more than likely. I had black smoke, black liquid out the tailpipe, smelled like raw gas. My Fuel Pressure regulator was shot. Common things are the Fuel Regulator or the Oxygen sensor.
