Maybe a touch high idle. It should be 900-950 when car has been driven for 15 minutes. That’s how long it takes for a total warm up. If you drop idle 150 then it’s sitting at 1850 for cold start= fine.
At 60-90 degrees cold start it should idle for 1-2 min at 14-1500 ish
Your modern Toyota will warm up at 1800 rpm for 1-2 minutes, you just won’t hear it or feel it

I wasn't aware that cold idle is that high...My 2015 X3 cold starts at maybe 1200rpm but is down to 800rpm within 30sec. I guess I need to remind myself that a 1978 fuel injection can't be compared to today's systems.
