Hey all. I have a 2004 350Z touring that has been giving me a LOT of issues as of late. Wife left to run an errand. got to the end of the road and said it started chugging really heavily to the point that she was scared to drive it home. I looked at it later and it wouldn't even start. it would crank until the cows came home but no start. got a VQ fuel port installed. says about 46 PSI. pulled the plugs, bad carbon fouling, stinks of gasoline. Changed them today. It will start only if you hold the pedal all the way down in flood mode. the idle is very erratic and rough. Exhaust stinks of gas. Here's the other thing. There is a popping sound when i push on the gas. very consistent timing and pitch. BUB-BUB-BUB-BUB-BUB. Like that. I have a video if i can upload it. and the pic is the codes i pulled on my MAC scout before i changed the plugs. Any help is greatly appreciated and i will answer any questions.

 

Didi you ever figure out what was the issue?
