Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
can someone tell me what coulor wire are on injector 3 & 2 pleaseTo diagnose is easy.
First disconnect each coil pack one at a time while the engine is running to find the missing cyl, replace that coil pack with another cyl's coil pack to see if the miss moves to that new cyl or stays in the same cyl.
If the miss moves then your coil pack is faulty, if it stays then and the spark plugs are good then its your inj which means your ecu has dropped out that inj due to a possible short from that coil pack.
Now to fix it without spending $1000+ on a ecu and tune
1. locate inj harness connection at the rear of intake manifold left side
2.if you look at the rear of the plug on the main harness side it should look like this.
brown/white pink/black brown/blue green red
yellow/black blue/black green/black
Cyl No.s
5 3 1 + +
6 4 2
3. Now lets say No.6 is missing, grab your test light and test No.6 wire but earth it on either the green or red power wires, the light should just stay on, you'll see after testing the other cyls that it should flash dimly.
3.now just cut No.6 (yellow/black) wire on the main harness side the splice it into No.5 wire (brown/white). its always good to splice it to the cyl earlier in the firing order eg No.2 to No.1 or No.4 to No.3. Then start engine
