FSM specs .031" or .8mm. Most run .032 with all stock components.
I'm currently running .035 with 8.5mm MSD Super Conductor wires (almost as conductive as solid-core but with minimal electro-magnetic and radio frequency interference), stock coil, and NGK v-power plugs. I've played around with different gaps and .035 works the best with my setup.
I used to run an MSD 6AL digital ignition, 40k volt e-core blaster coil, Super Conductor wires, and NGK v-power plugs...the same .035 seemed to work best with that setup as well. Ended up removing the MSD controller and coil since there was virtually no noticable performance or mileage increase.

Ok good information here from all. Yes I do run OEM everything on my 4runner so the gap will be .032, unless I need to toy with it. I have Autolite wires and plugs in it now from previous owner. NOT to wild about that. Hoping this changeover to NGK will fix the high idle and s!@#$$% gas mileage! 
. Anyways thank you all soo much. Hope this is not what they call high jacking a thread, but on the same hand supposed to post in an existing thread?

My chiltons book specs out a gap of .041 for a 93 3VZE... What gives? Is it a typo or should I use that gap? Looks like everyone else thinks it should be .032? I am just finally trying to get my engine ready to drop in my truck, and I want it to run when it's done!

i read a few interesting facts on spark plugs, i read that factory gap specs are not for optimal performance, but suitable for cold starting and smooth driving. sizing down the gap 0.010" is for people who run the motor closer to open throttle for better performance, while increasing the gap 0.010" is for people who run the motor at lower rpms for better performance and fuel economy.
i was thinking about running my plugs 0.010" more, has anyone done this?

ngk v power with stock gap work great.. Stock wires and cap, I will never use ngk wires again, they have a tendency to pop off the cap, I was constantly flaring the copper ends with a screwdriver to get as good as a contact that the stock wires have.

Just replaced plugs in Toyota Truck that had NGK IX Irdium plugs. About 110,000 KM's (68,000 miles), as well as cap and rotor. Cap and rotor where due for a change and was probably the biggest reason for a slight miss (50,000 km's). Plugs where worn and measured 0.042" to 0.45" could have reused but once they are out why not change. Ran NGK IX Irdium again, would not have a problem with Densco.
Girlfriends 92 just changed cap and rotor very big misfire was occuring, problem gone no miss but fuel economy is down. Did not check plugs, cold up here in the winter but maybe I should have. I believe I installed NGK V Groove, will look next time in town. But it's due for timimg belt and valve adjust this spring.

Still on the V-Power kick myself. Since posting here I've experimented with the gaps. Opened them up to .036", and saw noticeable improvement in power/fuel efficiency. Also was able to advance the timing two or three degrees further vs. stock gap specs(.032"). Still meaning to upgrade my coil from the stock canistor-type on the 88's.
BTW, I HIGHLY recommend those 8mm Accel SS solid-core wires. If you don't listen to the radio. MAJOR static if you do, no EM/RF shielding.
Sorry, sb5walker, but I beg to differ. And Toyota would too. Or why would they have later upgraded the ignition coil? Let's just say they nearly got it right on the first try. And there are gains to be had by upgrading ALL the ignition components, even on a stock 3vze, IMO.

what other ignition components should/could be upgraded?
