Re: '89 Cavalier 2.8L Z24 won't accelerate over 25mph, car just jerks.

I checked the spark on all 6 wires, and all 6 had a healthy spark. So I decided to check the gap on the plugs, and to my surprise one of the plugs was completely destroyed. On top of that there was a small amount of fuel on the plugs. I went ahead and replaced the plugs and decided to check the fuel pressure, pressure is at what it should be and the fuel pressure regulator is working as it should. I even disconnected the vacuum to the regulator and fuel pressure went up as it should. The car is also giving out a gassy smell, as if its running rich. I'm not sure were to go from here as far as what to check next...
