Just cleaned out my iac valve and was wonder where the 1uz is supposed to idle normally. It's a 93 by the way. Thanks!

Mine is right around 500-550, but I think that's a tick low. I think I read on here somewhere between 6-700.

That's without the AC compressor on. AC on, mine idles at maybe 800ish.

FWIW, my engine runs perfectly. No hiccups or anything to note.

600-800 rpm fully warmed up. first start up around 1100-1300. for me anyway...

Mine shows at about 3-400, and 200 with a bad coil! Then again, I have a SC300 dash, so raise those numbers by 33%. It's still funny to be at a stoplight and (with my exhaust) have it idle so low that it sounds like a lumpy-cam 60's muscle car. Gets the best looks.

Mine with a newly rebuilt ECU and maladjusted TPS idles at 1300 when cold, 1100 when warm. Should idle at about 700 when warm with A/C off.

I think mine is between 5 and 6 when warm (ill check today) but even after cleaning the IAC last week still sends my aftermarket volt meter into the RED (12v or less) when warm, in drive and stopped at a stoplight. 3 times it went down to 11 volts and died at a light with accessories on. I have to shift into neutral at stoplights and rev it a bit. It stays in the green much more often with the AC on. I am on my third alternator with a new battery. Is there another way to raise the idle a bit? Could it be my ECU?

Check engine grounds. Clean em up.
