1989 Honda Prelude

Dear brianjaco, are you refering to the firing order? If you are the firing orders for the 2.0 litre and the 2.1 is 1-3-4-2. If it is the same firing order for the 1.8 l or 2.0 sohc engines as well. Hope this helps if it is the ignition timing timing let me know and I will let you know where to look and how to adjust with a timing light. That is the firing order. The number of your cylinders run from left to right when looking from the front of the car is 4321. So the first cylinder closets to the distributor is the number 4 cylinder and goes down from there.
