Come to think of it, G Crankshaft Position Sensor Failure could also be the cause. That sensor sends conditioned Hall-effect signals to the PCME from within the distributor that the PCME uses to determine when #1 cylinder comes up on top-dead center (TDC). This sensor information is used to phase the sequential firing of the fuel injectors during normal SFI operation. This sensor is also known as a camshaft position sensor or CID sensor. It is a Hall-effect sensor located on the igniter in the distributor and it "fired" by a single-vane "wheel" that turns as the exhaust camshaft on the left (radiator)-side bank rotates. This code indicates that the G crankshaft (or camshaft) position sensor is not sending camshaft positional information to the PCME or the PCME is unable to make use of the signal it is sending.
When Code 3 is present, the PCME stops firing the fuel injectors in sequential mode and instead fires them in a "batch" mode since the PCME does not have any way to know where TDC on #1 is. This results in a slight loss of power and a lowering of the engine's fuel economy. but it could also be overworking the injectors, or doing something else stupid, you never know, and resulting in your cars issues. This code is memorized in the PCME non-volatile memory. So once you fix it, you'll have to clear the PCME to get the car to run normally again.
Check the condition of the 5-pin connector at the distributor. Check for +12V present at the R/BK wire to ground.
Check the seating of the 5-pin connector. Make sure it is clean and fully seated.
The igniter in the distributor is probably the most likely cause of this code although a bad PCME is not impossible.
