Excluding the DPFE/fuel pump from the diagnosis, I'd say it's the TPS sensor or the MAF. Something's causing the engine to believe there's more air than there is coming into the motor, the ECU signals the injectors to stay open longer, and you bog in your own fuel.
Eletronics cleaner for the MAF, then pull codes, or monitor the TPS/MAF voltages across the range from idle to WOT run. See what happens.
Problem is the car's more computer than vehicle... You need a computer to fix it (Autotap, etc.)
