I agree with Tom, first thing to check is the primary fuel injectors, then replace the oil pressure sending unit.
Fuel injector failure is fairly common in the early year cars, it's caused by ethanol in today's gasoline that eats through internal seals in the fuel injector and shorting out the coils. There is no "Fix" only replacement.
The oil pressure sending unit is another common failure item on early year cars.
