bizzare problem part II

[RPM427]

Well, I installed that EGR eliminator kit with the EGR simulator and I thought it was fixed. The car was running GREAT for 2 days then back to its same old crappy self. When I changed the O2 sensors a few weeks ago, the car was running much better, then two days later, back to running like crap.

I have checked everything! I am at a dead end. The only thing I can think of is it might be the computer. Its the only thing I can think of that would cuase the engine to revert back to the "crappy mode" after a couple of days. A few months ago I installed an new alternator that is OE on 94 stangs (130 amp). The voltage regulator was defective and peged the volt meter for about 1/2 hour. I had to take the output wire of of the starter coil cuase it was red hot. Would that be enough to fry my computer? This problem only started a few weeks ago. Is there any way to test my computer? My friend has a 90 GT, can I swap his computer into my car to see if it runs better? I am at a dead end. PLEASE HELP ME!
