I have a 1996 Lexus es300. Check engine light is on for various reasons. Rides rough and a vacuum line was disconnected/blown off. Autozone said various cylinders were misfiring and I here a slight knocking engine noise when I first start the vehicle and drive. I had them clear the codes, then drove it around, then rechecked and 1,3,5 were misfiring.
I found this thread and I think it applies to my year/model.

If the image goes down and somebody stumbles across this...the front of the car from left to right (when looking under the hood) is 2,4,6 (3 coil packs); the back of the car from left to right is 1,3,5 (no coil packs). I don't know the firing order, but I know what connects to what, 1-4, 3-6, 5-2. Very strange wiring, but my lexus runs like a top now!
My issue was bad wires...they looked fine, but they were bad.
