I just got my Cam Shaft Gears done under warranty and now i'm noticing a rough idle. I know that we IS250 owners have that constant ticking due to fuel injection, but now its even louder.

Someone suggested Sea Foam, but they never heard the idle, i'll try posting a video later today.

Till then, any ideas? Thanks.


Also, check out this poll ( https://www.clublexus.com/forums/aut...rl-silver.html ). I know that thread doesn't get as many eyes as this one, but i just want you guys' opinions! Thanks a lot!

 

If it only started after the cam
Gear TSIB was performed, take it back to the dealer and have them fix it. Do that before trying anything yourself.

 

I took it back to them, they said everything is normal? And i drive the car, daily, i know whats normal and whats not normal.
