      I have a 2000 with the 4.0L OHV. I used to know my firing order and now i need it because i think my plug wires are set up wrong. Is this it?

      cylinders on the engine are numbered

      so if i have a cylinder missfire i should switch out the plug that is on the drivers side closest to the front of the vehicle? And i connect 1 from the coilpack with 1 in the engine and so on and so on?

      The way I posted the numbers above is from the vantage point of you standing in front of the truck...

      Match the numbers...

      For example.. The back right connector on the coil pack goes to the front right spot on the engine...

      Also, it should be listed on the emisions sticker under the hood.. but from what I can tell, the firing order for the 4.0ohv was the same for all years.. 1991-2000
