Try the temp sensor for the PCM first.

Two wire sensor, should be right close to the thermostat housing. (which makes the sensor REAL fun to get to.....)

Huh? If the PCM gets bad information from the temp sensor, yeah, the engine WILL run like crap. If the sensor has completely failed, the PCM will think it is -40 degrees out, and positively DUMP fuel trying to get a mixture that will burn. Now, if it ISN'T actually -40 degrees out, that will flood the motor out in short order.

Was it a one wire, or two wire sensor? Did the parts store give you the right sensor?
