Cleaning throttle bodies

Trips · 06-12-2012, 09:39 PM

Just curious but couldn't you just clean them without having to take them out?

Thats how I've done it on other cars

Yea thats how i did it too with my previous cars but i think because the intake manifold on the Z is plastic, the throttle body spray might mess it up. Just an idea not sure though.

Just cleaned the throttle bodies out at 19,000 miles and you can see there was a lot of gunk and dirt on them. The backside was dirtier and took some scrubbing to get clean. There was also dirt particles in the intake manifold and I wiped all that clean with just a dry microfiber. I posted a pic of the microfiber towel I used so you guys can get a better idea of all the dirt that came out of them. The backside of the microfiber has an equal amount of grime too. I did notice that car idles smoother and the revs don't bounce as much when I come to a stop.

Hate to bump a thread that's a year old, but I can't find an answer as to whether its ok to take the TB's off the car when cleaning them or not. A lot of the info I can find is from the G35/37 group and some of them have issues with the idle after messing with the TB's.

For those of you who took the throttle bodies completely off the car to clean them (best way to do so imo) were there any issues afterwards?

I haven't done it but, as long as you don't mess up the electrical parts, I don't see how it could cause a problem. You will have to recalibrate the ECU/TBs but that appears to be a straightforward process. YMMV
I'm guessing that those with problems either did something to the electrical parts or their TBs were dirty enough that the engine had to do some re-learning after cleaning.

I'm with you on cleaning with the TBs removed. If they are dirty enough to need cleaning there is a risk of moving dirt into the manifold and engine. If I were cleaning them proactively (eg, every thousand miles), I would probably do it with the TBs installed.

How exactly do you recalibrate the ecu/TBs?
