Engine stalls when press throttle
I am having great problems with my 79 280zx. It will sit and idle fine all day but most times when you press the peddle the engine shutters and almost stalls. It also acts like it is backfiring through the intake. I recently replaced the fuel pump. I don't even know what to start checking with the fuel injection system. Any ideas would be greatly appreciated.
Thank You

Re: Engine stalls when press throttle
I don't know too much about fuel injection cause I have a 70' 240. I think it sounds like you need more air. I think you can disconect the air flow sensor from the throttle body, but leave the wiring connected, then floor it and see what that does. It might be that you need a new one, or you just need a new air filter. On a carbed Z when that happens your air to fuel mixture is wrong or the plugs are dirty or bad. Your timing might have something to do with it. LIke I said I don't know injection but that seems logical to me.

Re: Engine stalls when press throttle
It could be your throttle position switch, does it kinda bog down a bunch before it revs up, like it tried to choke and then hesitates? Well anyway, if it's the TPS, you have to adjust it, I"m not entirely sure of the procedure in a 280, but for a 300 you disconnect the plug and check the top 2 tines for continuity, and rotate the switch until it contacts... I'm sure someone can explain it better than that, but it's in the Haynes guide, and you can try that, costs no money to adjust the switch, if not that, then you can keep looking...
