Where should a 1uz idle (sc400)
#4
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.

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?
