White Smoke and Weak Idle
I have drilled and slotted on mine and what a dif they make!
New IACV seems to have cured low idle weakness. It idles high 80% of the time so it was hard to tell at first.
New TPS and VSS haven't really changed anything, but have ruled them out. I found I place about an hour away that says they have an Autologic system and can reset the ECU. I'll be taking it into them Monday and hopefully that will fix the high idle.
The misfiring may be the last issue now. Still getting P1313 and P1314. It seems to happen after a certain amount of load or after a certain RPM between 2000-3000. It can sometimes be fixed by pulling over and restarting it. Then it pulls strong and smooth through the entire RPM range. Other times restarting doesn't do anything to fix it. I'm guessing crank or cam pos sensor, or clogged CATs.
On a positive note; Grandpa and I went out in the green Oregon mountains today and had a good time shooting and light 4-wheeling. The only issue was on the way down the brakes overheated, smoked some, and had to pull over. Definitely have to get some better rotors.

Well it appears this is almost wrapped up. Took a trip to Henry's Foreign Auto (place selling defender) and he used Autologic to reset the ECU. Fired it up and it idles better than ever now. Only cost $20. It also revealed the P1313 and P1314 were coming from cylinder 1 and 6 so likely it's that coil pack. Feels great to know with some certainty what the last issue is.

Yeah the coils can be rearranged in the bracket. That would be a good way to verify it. Most places want over $400 for the whole coil-pack but I found the individual coils for $32 each.

Cylinder 1 and 6 are served by the same coil pack (dual coil). When one dies, the other holds hands and steps off the ledge with them....
