#1 Spark plug not burning the fuel
Hello, I have a 1981 Datsun/Nissan 280ZX non-turbo and the #1 Spark plug is not burning the fuel. All the other spark plugs are but that one is not. There is power going to the plug and the spark plug is working but the seem to look new and used, no gas burns, nothing and the car does not run smooth, lot of shaking at the engine. Please help. thx u.

Did you check the gap on the spark plug? even though you buy it new sometimes the gap is off? that could make it run rough. you can also try turning the distributer to adjust the timeing but i would check the gap first? also check the gap in the cap.
If you've checked wire, plug & cap, next is compression?
Did you try swapping plug, & wire (1 at a time) with another cylinder?
