you know what, I dont ever recall having that low idle issue after my TB was cleaned out. Before cleaning it, I did have one or two occassion where the engine was shaking and it wanted to die.
But I do not know of the problem well enough to decide if this is the cause because I dont know if it only happens to higher mileage cars.

3 of those holes in my tb were completely blocked. at first the mechanic thought it might be carbon, but a jet from an air nozzle didn't do a thing, and he had to resort to using a cleaner again.

i have over 70k mi now, and my tb was pretty bad. you could actually scoop the crud around the throttle plate with your finger

I've been here, pretty much every night. I just haven't been posting much lately. I wanted to make sure that I didn't pass your post count.

My idle is smoothher now. No more does the engine sound unbalanced. It use to have this weird noise at idle as if one cylinder was gone. After having this cleaned out, the engine sounds like music to my ears

I dont really know. Possibly because when you blast the black gunk in the TB, it might fall into the intake manifold. The engine probably wont have trouble burning it, but who knows. My throttle body was dirty anyways so I cleaned it up.![Stick Out Tongue](https://www.clublexus.com/forums/images/smilies/tongue.gif)
