spark plugs
they do not make spark plugs for 10,000 engines.
only heat ranges and size and reach. (and metals)
the gap is set by the factory machine (computer controlled) that sets the all near 0.045" 1.2mm and are used on 100s if not 1000s if different engines
your gaps are wrong.
and they NGK or other do not guarantee any factory gap, at all. (oem plugs , not magic snake oil , no gap plugs. aka , surface fire and all that )
i even have and email from them stating that.
Did you look it up. all g16s here run .7mm all do, because the coil is not a HIGH energy coil. it's just weak. and the gap must be lower.
on new cars with hot red hot high current coils, x4, x6 and x8 COP'S run huge gaps. 1.2mm works, to allow this but if a turbo the gaps shrink again, due to the huge pressures under boost. (what the do is balance combustion pressure to spark energy) with due care.
but your engine, has old weak coil 1 coil and cap ,rotor and long long wires. the spark is weak. (by today's standards)
on ours the hood sticker shows lash gap and spark plug gap;. in full view.

here is an international listing for tune up data.

Real suzuki FSM books spec them from 0.028 to 0.032 , (the true spec)
all shops use the lower number, why? , because they all wear wider so, set it low. and let it run longer,
wider gaps will cause hard to start car cold, and under huge engine loads, (hills)
if your induction coil is located on the fire wall or in the distributor, ours in the distrib and is weak. both are.
to get high energy ignition , it takes huge primary currents, and these cars don't get that until 1999.
and j20 engines up. with COPS. 4 cops. each engine and huge ignitor currents.
shacking is always misfiring, can be bad spark, flooding misfire, or injection issues. and even low compression.
each shake is a combustion failure, part or total. misfiring.
the gaps matter when cold and rich it needs narrow, spark gap to make it more powerful. (intense) to fire it rich.

I'm not sure where that other hole show in your photo goes, in the TB bell horn , left ? is that IAC path 2?
ok the IAC was rolled way back with restrictions. that would do it , for sure..
some TB may have just 1 slot,, IIRC...
