1993 3.1L V6 Firing Order

Does someone have the firing order for a 1993 Pontiac Transport 3.1L V6?

Also whenever I punch down on the accelerator the engine bogs out especially on a hill, if I gradually accelerate it runs fine andy ideas?

1-2-3-4-5-6

1,3,5 on the bulhead side of engine counted from belt
2,4,6 on the front side of engine ...................

I'dd check the TPS (throttle position sensor - a common problem) and the MAP (manifold air pressure) sensor...do you have any code? DO you know the procedure to get them from the CEL?

No service engine light is on, so I haven't had any tests run. I am not sure how to get them from the CEL can you advise?

CEL light will blink 12 3 times (one ulse of light then 2 pulses, 3 times) then will start giving the codes, if any, like 23 will be 2 pulses, then 3 more..Once finished, it returns to code 12.
