Re: Help with rough idle and acceleration - TIA
bac to the op what about the misfire??/ the easiest way to test that coil
pack is replace with a known good one have any friends with a 4.0 newer
than 2k ?same part number for all
4 13mm bolts hold it in place and one connector at the bac 5 minute job
without air tools

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).
