Mustang trouble
 

I'm having trouble with my '95 Mustang GT it will start and run for about 20 seconds then shut off. The problems started after the Jet Chip melted in the original computer. Had the coil, alternator and I.C.M. tested, turns out they are fine. Spark plug wires, spark plugs, and distributor have been replaced, and it was burning out I.C.M.'s.
Anyone have an idea what the culprit could be?

Has a BBK cold air intake with the standard MAF sensor, could that be causing the engine to run too lean?

Never heard of such a problem before. This is strange.
