Changed the following - fuel pump, fuel filter, computer chip, both ignition coils and ignition module. Also, a pressure test on the cat convert. was performed by a professional muffler shop. Engine will continuously loose power under a load until it just completely stalls out. Once stalled, it cranks for awhile before it catches, but is running rough until it finally revs up and blows it out. Three different mechanics have tried to diagnose it without coming up with an answer. Just passed the Califonia smog test. HELP!
