i have a 1990 300zx twin turbo when its cold it dies as soon as i start it and if you try to give it gas it kills it self out. when i get it warm its fine but if i drive it hard and get it hot it starts missing out at 5000rpms with wot and wouldn't rev any higher. but its doesn't at half gas it will go to rev limiter. at night you can see flams out of my exhaust.(i have no cats 2.5" exhaust). I have replaced tps, coolant temp senser,o2,cam shaft position senser, timing belt,spark plugs,idle control valve. is there something else it could be let me know thats
