I have been having some sort of power loss on acceleration for quite some time now and I can’t for the life of me pinpoint what it is.

2003 350z

Car smokes sometimes on acceleration. Sometimes accelerates normally. Sometimes the rpm’s stick and I can hear the motor going but it’s not going anywhere even with my foot to the floor or it’ll sputter then accelerate. Car smells like it’s burning gasoline or something. The car is gutted so I get the fumes all inside the cabin. No CEL at all.

I changed the spark plugs, cleaned the injectors, cleaned the throttle body and checked the maf. It’s not any of those.

Pls help. It’s really pissing me off.

Here’s a video of the problem.
