ETC in Liberty 07 is whistling

[slavu]

hello everybody,

the problem is already known (there is a TSB 09-001-07 dated on March 14, 2007), I've got Libby 07 and ETC whistles when acceleration (about 3-4k rpms).
I took my car back to the shop but they didn't repair this even having the mentioned manual. I'm already tired of them
So, my question is do You have any experience on that issue ?

I wonder if KK 08 or 09 models equipped with 3.7 engines have the same Electronic Throttle Body parts. Do they make the same whistle-like sound during acceleration ? They should cause the engine is exactly the same.

Maybe the issue is solved in those models and there is a possibillity to order a new ETC from KK and put to my 07 KJ ?

thanks in advance for any advice

Check the intake piping clamps to make sure they are tight,check for vacuum leaks.If all clamps are tight and no vacuum leaks found it's a normal noise and you have super hearing in the high frequency range.
