My 94 keeps I have changed plugs, wires, opti, coil, icm, and fuel filter. I really don't think fuel is a problem, because it smells like it is running rich. Wires are routed correctly. I have cleaned the MAF sensor with contact spray, and gave it the knock test. My TB is not that old and it came with a tps when I bought it.

Any help is appreciated.

 

try 02 sensors. I had the same problem, and it turned out to be 02s
