possible guel injection problem Help!

I need some help here. I have a 92 3000gt and when I'm driving now lately I will hear a loud clicking and the car will cut out real bad if the rpms aren't up in the 2500 to 3000 range it will die. Am I right in thinking that this is clogged fuel injectors or am I overlooking something else?
Thanks

check out your idle and then check your MAF or MAP whichever your car has also check out your fuel pump(s) try using an onboard diagnostics gen/level 1 or 2 good luck

Thanks for the reply. I've narrowed it down a little yesterday. It is electrical because the clicking happens with the engine off and it is happening because of a signal comeing to the throttle body because when I unplug the wires from it it doesn't click anymore. It has also gotten much worse.
