I searched the forum and there was a thread while back about engine vibrate or UNSTABLE at idle. Here's the link: https://www.clublexus.com/forums/sho...d.php?t=300201

My car did the same thing today. When I came to stop this morning, it vibrated, and its idle speed was below 600rpms as if it's going to stall.

I remember a few months ago, when I backed up my car out from the garage, all of a sudden, the engine just stalled.

Is there anyone out there has this problem and any resolutions from dealer? Or is there even a TSIB for this? I will take it to dealer for sure, but I want to know before hand what's happening to my car?

Mileage: 25k
Engine: automatic
Vibrate in Morning (about 65F)

Thanks

 

Sounds like a side effect of the cam gear TSIB. That's what I'd look into.

 

Thanks for quick response. I'll go to dealer today. Could you point me where is the cam gear TSIB?

 

Hey Lobuxracer
Is it possible to show me the TSIB for this side effect?

 

Could it be the fuel injector/s? Happened to my son's car at idle. Turned out to be a broken fuel injector.

 

I brought mine into the dealer to have them check it out today. They said that they have never heard of such problem for IS250. Does anyone have a copy of the TSIB? Did a search but nothing came up.

I'm not sure about some of you guys that have done the engine rattle TSB but for some reason my car, when driving, there a bit more whine to it. Is this normal?
