when the car gets warm about 200 deg it will idle ruff like it wont push fuel and it will die. then i have wait for the car to cool before i can start it. this is getting very frustrating. i dont know what to do anymore

g35 coupe
Hey did u ever figure out the problem, I have the same year car with the same issue
I have the same issue , and success fixing yours
first off i have a 06 coupe 5at and turboed. my issue just started last thursday. i was driving home from ohio when this started. i would give the car some gas to pass cars or climb a hill and when the boost gauge read 10 vac the car would bogg and lose power. figured it was bad gas so we stopped to fill up. went to turn the car on and it wouldnt start. after about 20 min it started but barely idled. i got pissed at the ruff idle and just put it in drive. after about foot the idle smoothed out and ran fine.
when i drive the car for more then 15 miles, it takes it forever to start. first start up of the day it cranks a couple of times then fires right up. car has new plugs (step colder) and fuel pump (not stock). im out of ideas and any help will be great.

Check all your turbo pipes for leaks, check the A/F ratio, something is out of whack, pull the spark plugs and inspect them, etc. Get the fuel damper sandwich plate from Z1 Motorsports so you can watch fuel pressure while the engine is under load.
Who did the tune on your vehicle? Was it an Uprev tune or a plug-in module?
