Hey ladies and Gentlemen. Im new to this forum, Ive had my Nissan 300zx twin turbo z32 for almost 2 years now and still trying to fight this problem. If anyone can help out and help me find this problem thats been haunting me for years that would be great. The problem is that when you start it up it runs ok when its a cold start, You can hear it kind of misfireing and the idle goes like down and up so small though that you cant even notice. When the car is warm it starts idling a little more rough. When you drive the car it drives awesome and runs great. Pulls hard all the turbos work and everything. just that when you turn the car on when the vehical is warm it takes some time to start and ill have to give it some gas with the pedal to start it and keep givin it gas to stay running. But driving it it drives awsome. Thanks

 

anybody please

 

check the plugs going into the coil packs. The tabs were broken off of mine and caused a rough idle and two dead cylinders. Push down on the plugs and if they push in then they were loose and you should order new ones.
