Can someone tell me the RPM's the IS 250 runs at in D after warmed up with no lights or a/c on (idle kicks up when they are on)? Also, what are the signs of failing motor mounts? Still trying to figure out why my car continues to have the steering wheel vibration in gear. Dealer says it is normal as no codes showing up. They already did a major valve cleaning.

 

mines reoun 700 - 800, but i cant confirm right now cuz my cars get the smash repair

but when its cold it goes up to like 1000+ then drops down after the temp drops a bit

 

Hmmm...I was wondering the same thing. Mine kicks up to around 1400 on a cold start and then drops to about 1000 when it's warm.

 

i remember mines definatley under 1000 after it gets warm

but it does kick up around 1400 when its cold (rarely tho, cuz its so damn hot here in australia, lol)
but its getting colder recently
