Hey guys.

So I have a kA24E, and it shakes at idle. The idle is at 800rpms. I just put in new wires, adjusted the distributor, fuel pump, new thermostat, coolant flush, brake fluid flush, replace transmission fluid, and rear diff flush, and oil change.

The car was sitting for just about 1 year, so I ran some Motul Fuel Cleaner and filled her up with 94. It still shakes at idle. The car pulls pretty good. I do have a cone intake. It tried unplugging the MAF and the car dies.

Any idea whats going on?

Do you have a broken, fatigued or loose motor mount or transmission mount? The spark plugs might not be gapped right. A loose timing chain can cause erratic idle. Before you take apart the timing chain, check the other things, because its alot more work. It could be something else, this is just a few ideas off the top of my head.
