He was spraying fuel in the area where the muffler would be, cranking an engine with no oil, pumping fuel into the trunk, driving with loose bits of glass, sitting on mold, having bare wires where he was pumping fuel, etc.
He left a "cherry" Fiero out to die. The sunroof was long gone, stuff was growing up from the floor boards.
While running the Fiero, he left the return line loose to dump fuel onto the muffler.
After having all that garbage in the throttle body, he just lightly blew it out, then started it, leaving the remaining garbage to be taken into the engine.
He put bad fuel into the engine.
The Fiero I just sold was not quite that bad when I got it. The windshield was intact, and there was no hail damage, but the marker lights were gone, and the steering was all messed up. It needed many of the same things this one needs, which is much more than this guy lets on.
