Thanks all for the help. Replaced about 80% of the lines, mostly anything that attached to intake/TB/dizzy, still have a few more feet i can swap out. Emission codes are gone already tho. I also maxed out the timing and put in 93 octane. Does everyone ka24e's distributor max/min at the same numbers?

Is the red thing in the video the valve cover? If so, there are holes in it. Won't that cause a vacuum leak?
That was my truck when I had a bogging issue. Unless I missed a different posted video. Yes that is the passenger side fender. BTW it's fixed thanks to JPCode and his troubleshooting expertise.

They would be roughly about the same, but it's just a bolt adjustment. There will be deviances depending on the bolt condition, how much garbage is in the bolt-slot, if the bolt-slot has been wallowed-out (is that a real term?), etc.

If you can get it back to normal timing settings of about 14* BTDC, you should be able to run the cheaper 87 octane without pinging. 87 should* give you better fuel mileage and cost less and produce fewer emissions.

*Note: SHOULD. It doesn't always.

If wallowed is not a real term, i know many people that wouldnt believe it.

I never noticed a ping. Even at 87 and max advance when i drove to the store (under very light load). Is a ping louder then the lifters usually sound? And it would be 1 loud ping, not consistant right?

Wheres the swirl valve at? Is there a way to modify it to keep it on? I just would be happy to have it working, but figured id ask.

Ping sounds like clattering when you press the gas pedal.

The Swirl Control Valve should be pictured on the bottom image:

Have you by chance looked at the charcoal canister under the bed above spare tire? Check the hoses, connector and condition of the canister.
