1990 Running Rich
1990 - 132000 miles. New air filter.
Pretty sure it's running rich, it blows black smoke when accelerating and leaves black deposits all over the bumper.
Haven't pulled the plugs yet, and I don't know when they were last changed so I will do that.
I was just wondering if anyone had any suggestions as to how I can fix this.
Thanks!

Thats a likely possibility...
But isn't the problem originating before both the catalytic converter and muffler?
If the cat really is crapped out would it cause the engine to run rich?
The o2 reading is before the cat anyways so wouldn't the problem be coming from a different source?

No warning lights, seems the same as before the replacing the filter but I can't be 100% sure since I changed it right after I got it.
I just remembered the PO said the head had work done to it. Twice. The first time it was done crappily and the second was to fix the crappy job. I don't know if this would contribute to the problem.
