While warming up, I have to goose it to keep it running.
It runs great, almost perfect once it is warm.

I've replaced/checked the IAB, TPS, ACT, ECT, MAF, fuel pump, coil, fuel pump relay, and looked for vacuum leaks.

How do ya'll have your EGR's blocked off? Since I have all emissions stuff removed can I just disconnect the EGR valve too? Or does it provide some reference signal to the EEC-IV? I'm frustrated at this point, it's been happening for a week now.

The system looks for a closed voltage value from the sensor of .2vdc or higher, if you have the plunger all the way in, it's reading over the max value for a closed valve condition. There is a resistor plug to get rid of the valve but still provide the ECM with a "good" voltage reading, don't have the details on how to get one but maybe one of the guys can help you with it. You could also zip the plunger to a position where the signal reading stays above .2vdc and take care of that concern.

On your idle/cold problem.......have you checked the system for codes? If so, can you post them? It will give us more info to help you solve the problem. LUK
