Is it possible to lose two fuel injectors at once. I rarely drive my z but about a month ago I taught my 16 yr old how to drive a 5-speed and literally let the car sit until 2 weeks ago and started it up and felt like it was running on 4 or 5 cylinders. Im no mechanic so with car running I lifted off plug going to each coil pack and two of them make no difference in the incredibly choppy idle. I then took those two coil packs off and swapped em with cylinders that were running and its not the coil packs. We did drive around enough a month ago that we needed to buy gas. any help would be appreciated on the multiple injector failure idea I have.
