KA Won't idle after clearing CEL

**Update 11-23**

Rebuilt KA24E now has close to 5k miles.
Only issues: Idle hunts between 600 and 900 rpms, CEL is on

Yesterday (11-22), I pulled the code: 32 - EGR function.
Cleared it in ECU without replacing EGR.
Idle screw in ECU in same position before I did diagnostics
Now the car stalls, won't hold idle.
Borrowed a vacuum tester from autozone, the tube is too big for the EGR valve so I didn't get to test EGR valve.

I have the EGR valve on order, will get it Friday.

Any other parts I should look at? Thanks


**Update 5-10: Now with spark and timing redone 5+ times. **

This is the 3rd sohc i've swapped in my '89, the first as a fresh rebuild. The other two were used. I'm not getting any spark. The first 2x that I've swapped in a sohc, it started right up.

It has:

new spark plugs
new coil <-- after doing search
spark plug wires are still pretty new
it is getting fuel
wire connections checked/rechecked

I've tried: 2 different distributors; 2 different distributor caps; adjusting to Top Dead Center (TDC) 1x sunday, 2x today
Car ran before the swap, but had a bad head gasket, which is why I got a rebuilt engine.

Any help would be greatly appreciated.
