JustinOlson Posted February 3, 2008 Share Posted February 3, 2008 So my 280z runs really bad when it is cold. I can get in it and give it full throttle and it wont rev over 3000rpm. If I try to drive it it bucks and hardly will rev over 2000rpm. It sounds like it is missing on a few cylinders, but I haven't checked the spark. Anyhow, if I let it warm up for 5-10 minutes, it runs great. Revs smooth to 6000rpm and makes good power. I'm really confused on this one. Any ideas? Also the temperature gauge and oil pressure gauge work in the cabin. Do these use the same sensors that the ECU uses for cold start?
