I'm Redline

I have a 1996 Zenki. It has sat for about a year before I got it at a body shop. Body/Paint is immaculate, but it has some random mechanical issues that I am resovling as they come up. Last one as of the other day:

Hard to start first start of the day
Won't settle into idle(this is random)

I know older V8's and old Datsun's without ECU's and all teh other related stuff

Would this be a MAF issue or is there somewhere else I should look?

What I have done so far:
Check plugs, gap to .035, no fix
Air cleaner inspected, filter new, no issues here
Cat back installed, this did not cause issue
Replaced four cradle bushings, not part of the issue


Something tells me this is really simple. Also, when doing a basic tune up, it's plugs, wires, and distributor cap, IS THERE a RECOMMENDED GAP for the plugs?
