Shiboh Posted November 11, 2021 Share Posted November 11, 2021 My 1983 280zx n/a is misfiring at random times. With the timing light I can see the timing mark disappear at random times. This is causing my self tuning ez efi to run rich and stall. I replaced every single thing in my fuel and ignition system as well as all the gaskets on the motor and really have no clue what to do next. Has anyone on here ever had this issue and could give me some guidance? I just replaced the ICM and coil today for the second time and saw no change. I really can't afford to keep throwing parts at this thing Quote Link to comment Share on other sites More sharing options...
deisla Posted June 21, 2022 Share Posted June 21, 2022 (edited) What do hot spots mean on a sensor? I’m currently having a misfire situation on my nissan 350z after a valve cover job. I made sure I connected everything together back to specs also checked the plugs and they were good. 192.168.1.1 192.168.100.1 Edited June 23, 2022 by deisla Quote Link to comment Share on other sites More sharing options...
