I have the TB off right now, and was just curious... did anyone clean/wipe down the inside of the system past the TB?

it's also just as filthy as my TB was so was just curious

Here is a pic of what i'm talking about, i didn't touch it and just put the TB back on since I didn't see anyone talking about this...





Dirty






Clean






Also cleaned the air filter, she should be breathing a bit better now

Yes I wiped down the engine side of the throttle body inside. I didn't go too far, but maybe a few inches

But now I have some kind of whistle. Not sure where it's coming from?

Question!! Just cleaned the throttle body and installed a throttle body spacer. When I started driving down the road the gas pedal stuck and wouldn't release for a few seconds. Same thing happened when I installed a CAI. Any idea what it could be? Happened one time after the CAI and hasn't happened since until now. Any ideas????

Did you disconnect your battery to reset the ECU? I've had to do that whenever I've modded intake or TB on Fuel Injected motors since they're getting more air now then they were earlier.

JethroJK08

Yes, I disconnected the neg to reset the ECU. After a while it finally went back to normal and didn't get stuck anymore. Thanks

No one mentioned needing to replace the gasket between the throttle body and where it mounts. Is there not a gasket there? Is this old school of thought?

Delux2769

Nope, no gasket. Very nice. Jut takeoff, clean, then reinstall.

Well, I did a little research on this after I posted the question on this thread. Delux, you're right, there is not a conventional gasket between the throttle body and the intake manifold. However, there is an o-ring (technically a gasket but in this case acting more as a seal) that seals the throttle body to the mount. Not to worry, this part does not need to be replaced according to the local stealership I talked to this morning. BUT, If it looks dried out or damaged, make sure to replace it. You can get them (fel-pro) for $2 at your local parts store. Well worth the investment.

Good point JGP4JK, I don't think I noticed the o-ring the last time i did this.

Thanks for looking up a replacement as well.

You're probably fine man. Apparently the old school of thought of replacing the gasket every time you take the part off no longer applies. I wouldn't worry about it.
