2011 24k is250 at the light, car has been on less than 10 minutes and the rpm's started dropping below 300 maybe 200....... I'm like " don't even tell me " this is new for me sooooooo WOT time! And I usually open her up to about 6k when getting on the highway but Smh I'm confused
So soon? I've read this happens to some guys here


Sigh....

 

It could something simple like your battery going bad and causing symptoms like what you described. But @24k miles? Thats is just odd? Check to see if you still have warranty

 

Any recent work done under the hood? Unfortunately you wouldn't be the first relatively newer IS250 with the carbon build-up issue. Most experience the same stalling or near-stalling condition when reaching a stoplight.

 

I hope it helps but I did some runs getting on the highway today. Felt good we'll see how it goes.

 

^Glad you're pushing the motor; I feel alot of the carbon build-up issues have to do with folks not "pushing" their motors AND short commutes.

 

sounds like possible EGR valve - have it maintenanced, very inexpensive procedure.

 

Do IS's even have EGRs? Sounds like the carbon buildup

 

PCV, yes; EGR, I don't recall reading/seeing one. But we do have a charcoal canister.
