Ok... I've been dealing with this ordeal of getting my car fixed for the past month. The final analysis was three injectors blown, so the fuel regualtor, injectors, rear fuel rail, injector harnesses, etc. have all been replaced. The mechanic calls today and says that all functions of the engine are working fine now (after leak-down compression check, etc...), but now there is an extreme loss of power. He seems to think catalytic converter, could this really be the problem or something else?
