First, I should tell you that this car has a 318 cubin inch, 5.2 liter engine - 2 barrel carburetor, an electronic full control computer, (Holly carburetor - 6280) - lean burn engine. This car has low mileage.

My question: After getting warmed, the car will cut out and acts like it has intermittently no spark and also feels as though it's running out of fuel. I have put on a new gas tank to make sure that it's clean. Also, I have replaced the fuel filter, anti knock sensor, air temperature sensor in the manifold, oxygen sensor, magnetic pick up in the distributor (single pick-up) and also replaced the fuel control computer, unit # 4288576.

I have also rebuilt the carburetor and made sure that everything was working properly except for the electronic metering which I could not get any longer. After replacing the fuel control computer, the car now has a severe knock on slight acceleration and the car still cuts out as previously described. At times the solenoid in the engine compartment for the EGR system mounted on the firewall starts to sporadically operate. When this happens, the car begins to miss out severely. The EGR system is all controlled by the fuel control computer mounted on the side of the air cleaner.

Is there a reliable source that I can get a computer from? I feel that this could still be the problem or could you provide me a list of parts to change this over to a non-routing (that will still legally pass emissions)? Any other suggestions that you have would be greatly appreciated.
