loosing a cylinder i think

[Dumondti]

i have my car at 14psi and i has run good up until now. when i hit the gas and go into boost it will pull hard then sometimes (actually alot) there will be a jolt and sometimes back fire. i can sometimes pull through it but the other time i cant and have to let off the gas. i mostly happens when i go into boost mainly higher boost than 7psi. i have the walbro fuel pump and the 300zx tt fuel filter. but i am smelling fuel in the exhaust if i stop and park right after a bad pull

any thoughts spark plug, coil pack, injectors. help please

is this a recent swap? or has it been fine until now? If its a recent swap, check the coil pack wires, sometimes the one closest to the firewall is damaged when shipping/installing....but thats just a suggestion

Fuel cut maybe?

Could be a bunch of things.

Injectors (but you are running rich so scratch that for now)MAFS (try cleaning it, more boost means more air is thrown into it)Coil Packs or even Ignitor (if you can't burn the fuel you will smell it)
