canammx1 Posted February 5, 2012 Share Posted February 5, 2012 (edited) So it is pretty cold here in Central Oregon. I drive an '83 280zx non turbo. I am not great mechanically with cars. But I do work on bikes a bit. When cold the car seems to be running rich. Having to warm the car up is killing my gas mileage. When I start it up it makes a huge exhaust cloud until it is driven and cleared out. If anyone has any incite I would appreciate it.

tecreatta Posted February 6, 2012 Share Posted February 6, 2012 Have you tested the cold start injector? Quote Link to comment Share on other sites More sharing options...
