I have bought and installed viper igntion coil part# uf412 -B2918M
And jegs performance wires 40219 and i did the same as you guys installing 1&6 at the bottom, 2&5 middle and both flipped and non flipped 4&3 at top
The engine started but not smoothly
The problem here there is a lot if vibration that shake the car body with it and i have no clue what is the reason

Could be the wrong coil ? Or wrong wire ? Or bad pcm ?
It Can not be the spark plugs because i reused the coil rail and the engine started without problem

My jeep is 2000 tj 4.0l

Sounds like it is either hooked up wrong, a problem withe the wires, or with the spark plugs. Any codes for a misfire?

What is the thing you have by the dipstick?

A slight update on my setup:

The cut to length Summit wires worked fine until I installed a ham radio in the XJ. They aren't insulated that well and were creating static on the radio. I replaced them with a custom set of Magnecores.

I just finished doing my coil rail swap to a coil pack and I love how it came out. For anyone looking to do this swap I highly recommend it. I did however take it a step further by using an actual performance coil pack. My set up is a Davis United ignition screamin demon coil (part number 31740) msd 8.5mm wires and msd spark plugs gapped to .05. I’ve had it on for about a week now and there are 0 problems. Runs super smooth, starts right up, better throttle response, bit more giddy up through out the rpms, and I’m actually getting about 1-1.5mpg gain. The coil recommended running a .065 gap so I have a bit more experimentation to do. Also recommend paring it with 24lb/hr 12 hole injectors from jeepinjectors.com for the better spray pattern. I have a 2002 Jeep Wrangler TJ and this setup runs flawlessly
