1999 Lx-470 Rough Idling

[austinls]

I bought this vehicel as Lexus certified. The day I picked it up at the delaer I commented that it idles rough. They said it is normal.

I took the vehicle to another Lexus dealer who advised me the throttle body needed cleaning, which was not warranted, and I agreed to have done. No change in the idling.

15,000 miles later I took it back to the same dealer, complaining again. Without looking up my record, they said the throttle body needs cleaning. I declined and they knew nothing else to do.

I have owned 7 Lexus, 3 LS-400's. I still have a 1999 LS. ALL these vehicle idle smoothly.

Is this an inherent problem with the LX? Any suggestion to fix it?

It is still under Lexus warranty.

I have an 1999 LX 470 with 37,000MI and it idles smoothly. Your LS 400s idle smoothly and so should your LX470. Their is really no excuse for a vehicle of that caliber not to run like a top unless abused or requiring service. Try a different dealer maybe.
