as above, my idle is like 150 rpm after replacing the motor... wow that was expensive! I want the oil pressure and idle higher after that bill.
where is the screw to turn the idle up (1 Viewer)

Screw... None. Idle is controlled by the ECU via the idle control valve.
On first start after ECU has forgotten things, idle will be strange for a bit, have you restarted the engine a few times? One assumes that EVERYTHING is connected back properly...

Adjust the throttle cable for idle? That's always been a big no no.
I would verify the timing first.. go-to page 446 on the PDF fsm and you will see

first start after a month long dead battery. I was starting it once a week with the remote start. 1993 cruiser.. I am thinking that the remote doesn't turn every thing off.... two weeks and battery was so dead that not even the dome light glowed. I started it and let it run for a hour or so.. idle at 300. hour later went out to start it and the idle was 150. But as a Toyota it kept running but the oil pressure was down between nothing and the 1/4 level.. it usually runs in the middle.

oh every thing has been good for the last year. just kids stuff has been so busy it has been sitting... a year ago with the new motor it was my daily driver.

maybe it has just sat for too long. I want the cold or hot idle to be at least 800 cold and 600 hot.

Again, the idle is controlled by the ECU. It will do what it wants regardless of what you want 
The control is via the idle control valve. This is how FI vehicles have been 'doing things' for a few decades.
I'd suggest you check that everything is intact under the hood. Sitting there allows critters time to nest and chew on things they shouldn't.

If the battery has been disconnected or totally dead, then the ECU has completely forgotten the normal parameters for running properly. It may take a dozen or more start ups to learn what it needs to run right. One of the 93s we often work on usually takes 30-40 starts to get it to settle down.
Agreed. I recently disconnected my battery to clean the posts and upon start up the engine immediately revved up to 2,000 rpm. It stayed there for about a minute and then dropped back to about 1200 rpm. It took 6-7 more starts and a couple trips into town before it settled back down to 650 (engine hot no A/C).

^ you can add some vehicle details to your signature in your profile. Then it's always there

I am not sure it is not showing up like yours.

Every time the battery on our '93 gets disconnected for a longer period of time (for whatever reason...), afterwards the ECU "thinks" 200rpm is good enough for idle. What helps is resetting the IAC by turning the key from "off" to "Ign on" (without trying to start the vehicle) for 15 times within 20 seconds (this is not my input, it's according to this board, but I can't remember the post...). Sounds whack, feels retarded when you're doing it, but it helps, perhaps not on the first try, but usually on the second.

Above the search bar (top right area of this page) should be your avatar/account. Click on it and one option is signature, click. Fill in the box with stuff and it should then appear.
cheers,

you should also clean the throttle plate, if its dirty I can cause a low idle after the battery has been disconnected
