Anyone here ever take their intake manifold off?

I'm thinking someday I'd like to dig deeper into the manifold to clean out all that carbon. Car would run ALOT better I'd guess.

Lee, although it wouldn't hurt (assuming proper R&R) I doubt you would notice any diff in performance.

Did you see the pics I posted on the 98+ VvTi manifold?

Yup sure did.

Just wondering if anyone here had any descriptions about how to do it or pics.

(proper R&R ??)

Hey Lee ,

I wouldn't screw around with it if I were you.
If you don't get it right when you put it back
you can end up with a "vacuum problem" causing
a bad fuel/air ratio. Just my 2 cents worth.

Being a mechanical engineer doesn't mean I'm a mechanic.
I've done some work in the past on diff cars from tune ups
to dropping trannys, but fuel delivery components I don't
like to mess with especially with no performance gain.

If you are brave enough, there is a "TRICK" to shimming
the throttle body position sensor to effect some gain on
performance. But too much and it WILL cause havoc on the
tranny and fuel /air , etc.
It was posted on a SITE called LADMAN LEXUS
a few years past. I don't know what ever happened to him.
But I think he was out of the DC area, too bad he was good.
