i got a 1990 nissian 300 zx twin turbo, i got a week now. just purchase it from a guy who dont know nothing about cars but i do know a good bit about cars and basics, the motor idles rough, no check engine light is on. the motor sounds missing, from front view of motor. the left side feels more hot then right side. i took out each injector coil and check them by unpluging the harness and motor runs rougher and i connect it back and roughness goes away but i thought it was my left 3 injector when i pull out harness it dont do nothing so i thought it was my wire , i use a wire tester to test it and it has power. bulb lite, i swap the injector coil to the middle and start back the car and unplug the middle injector from back. and it trimbles so my injector coil works. i check each spark plug and they all look good. except gaping the plugs. what should i do next ? please help me out. iam new here. thanks to the Z club.
