Welcome- have you pulled any ECM codes yet? Throwing parts at a car is rarely successful, but figuring out what the diagnostic system is telling you always helps. It also helps to list your mileage on any threads asking for assistance.

I second the codes it would definitely help narrow it down. I'd guess possible bad relay or wiring short somewhere.

Just keep throwing parts at it - no point in checking the codes. I can't believe the lack of common sense I see in threads here like this one.

There's the problem - your back wheel is falling off...


But seriously, you need to provide more detail. A bunch of parts? What parts. What do you mean by a loss of power? Does it rev cleanly to redline or does it sputter or only go to 4000?


Otherwise we're pissing in the wind hoping to hit the bowl.

Dang, just looked up Vortech and their 350Z kits. Not bad. Makes me think it's doable.

How does a flywheel solve powerloss?

Is that like when a butterfly in Paris causes a many in New York to die?

I guess you can continue not throwing parts at it. Try changing your brake pads, your shift ****, your windshield, and then your air freshener and see if that helps

What wold You do if your car was messed up and had no codes no nothing to work with... Not even the dealer wants to take a look at it because it's not stock

I didn't buy any body's problem... My dad owns a shop I did all the work my self and the only thing the fly wheel did was turn off my check engine Vsc and slip light, because one of the toothache of the flu wheel was chipped a little so it was giving bad connection to the crank and the car revs fine but my car full throttle has no traction of I accelerate to the floor I feel like the gas is getting cut off

I'd take it to a shop where professionals who know what they're doing can properly diagnose and fix the problem.

So is the throttle cutting out, or are the tires spinning cause of no traction.

Scan tool with live data, I would look at knock
