Re: Help with rough idle and acceleration - TIA
The 3 coils dual-fire the spark plugs on cylinders
1–6, 2–5 and/or 3–4. When one cylinder is being fired
(on compression stroke), the spark to the opposite
cylinder is being wasted (on exhaust stroke).

Re: Help with rough idle and acceleration - TIA
My point is that if you have a bad coil you will have 2 cylinders
mis-firing.
