Was wondering if anyone knows what the warm idle should be in a 2013 460, foot on brake in drive? Mine is about 900rpm's seems high? Thanks ahead of time for any input! Cheers!

around 600... 2012

Yeah....900 high. Should idle at 500-600 in drive.

I notice if I turn things off (before shutting off the engine), that the idle will drop to like 500 rpm. Seems like if the last thing I turn off is the seat cooler, it will drop. I frequently shut things off before turning off the engine because when I was in my youth, I had a car that had a weak battery (and I had no money), and it wouldn't crank if it had a bunch of electrical things going. Like the radio, the fan / AC, a door was open and the overhead light was on. But if every load was off, the starter would turn and the engine would crank. That's stuck with me. Plus, I like it when the car cranks and everything is quiet, except the engine / exhaust. It just sounds nice to me. That's how I've come to notice the drop in rpm.

900 with foot on brake in drive and 500 with foot on brake in drive with air on. No air on in park 850. ?

roadfrog

Yep.....WAY too high.

Nospinzone

Agree. But now I'm wondering how that could happen.

cschmatz, if you take it to the dealer I would be interested to hear what they say.

roadfrog

Only things I can think of would be a dirty intake that's causing sticking of the throttle, ECU reprogramming and IAC motor.

Service agent said Tech checked it and was fine? Still seems high. Maybe Tech was high?

roadfrog

LOL. Yes....perhaps he was. 900 when completely warmed up, is too high, plain and simple.

Mine is 900 when I start my car for 1 min on park

Then I start to drive, 600 when idle on brake for traffic light, 5 mins back to parking lot, 600-700 on park
