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?
