94 zr1 missing @ start up (help!!!!) - ZR-1 Net Registry Forums

My 94 mis-fires at start up. When warm the problem goes away. I do have a 02 sensor code. However, the system is open loop when the motor is cold. Thus I do not belive that this is the problem. Also, at start up, its running a little rich. I was thinking that leaky injectors could be the problem, but, the same problem exists if I park the car for a week. I'am thinking that this is ample time for the fuel to evaporate from the cylinder. Therfore, I do not believe that a leaky injector is the problem. Any ideas?

Thanks
Jeff
