H3 TB and MAF Cleaning

[Medic_Morgan]

So I finally decided to clean my TB and MAF today after getting a replacement OEM Air Filter. I've done this to my wife's Honda and noticed a huge difference so it was the Hummers turn today Was a simple process/task to complete, as I've noticed a lot of the Hummers maintenance is. So I've got pics of before/after as you'll see the difference in my "liquid scrubbing" hehe but I do have a question about the TB. Is the TB Flapper supposed to have such an aggressive/steep tilt to it(see pics)? I was never really much of a mechanic on cars(only motorcycles) before the Hummer so a lot of what I've learned has been researched on our many Hummer forums. Hope I can get a clear answer and thanks for the help guys(and girls)

i just did a quick image search and that looks about like some of the ones listed. other styles do seem to be almost level when closed but a lot of those have dual ports . just put throttle body in google images and you can see what i mean ... :cheers:

Thanks Neo! I looked up some of the polished ones on eBay that the guys from 355nation sell and they look similar. It just looks as if mine is a little more "open", due to that little slit that you can see light through. After the test drive I did notice a BiG " seat of the pants" feel in acceleration. Definitely recommend this to everyone.

not sure if closing all the way is really neccessary, as long as it opens all the way under wide open throttle :thumbs: seat of the pants is what it's all about :cheers:

Looks identical to mine. Mine also had that little slit at the bottom. I was wondering about that myself. It definitely helps..

Yeah it opens all the way if I mash on my lil skinny pedal w/ my big boot After running around town and into work this morning I noticed smoother shift points, lower idling RPM's and I'm hoping to see an improvement in MPG's w/ the clean filter/TB. Now I just have to devise a new intake tube set up to remove the ugly GM Resonator. Would love an AirDoc but wanna save some $$. Anybody have ideas for an 08 I5?

Just my figger in, is that it's at an angle so it opens faster or allows more air quicker but already being at that angle instead of flat. The "slit" is for idle control, you gotta have some air getting by.

Medic I made some since bout 2006 that also will work on the 08 and a different one for the Alpha, it's not rocket science, maybe Redneck science?
