By to much fuel, are you saying the pressure is way high? If so, your fuel pressure regulator may be bad. I would pull the plugs and check them. If they are black then your running rich.

The AFR is controlled by several sensor. First, the air intake temp, then the MAF, and finally the O2 sensor. But also the engine coolant temp and the MAP. If the engine is going rich after up to heat I would think the ECT sensor may be bad. A test you can try is when it'* running bad, unplug the MAF, the engine will stumble as it switches from live data to internal tables. If the problem goes away, the MAF is the problem. Another thing I would suspect is the O2 sensor. With you having past problems causing it to run rich, this can over whelm the O2 sensor and wear it out.

i have a 1994 bonneville and when it hits operating temp it sputters really bad and wont go over 2000 rpms and will stall when i let off the throttle. i have replaced the crank sensor the cam sensor the knock sensor the tps the coil packs and the maf with a known working one and the icm. my fuel pressures are good. i even run the gauge while driving and all is good. i am at a loss and i am gonna try replacing the ecm. the issues your having sound kinda like mine.

If I remember right, that year is one that has known ECM problems. Also, did you replace the TPS correctly? It done wrong it will cause problems.
