If you can flip your throttle body plate open then you've got a problem. It is electronic so it should not move. And no, you cannot clean the TB properly unless you take it off. So you are saying that you can move your tb plate?

 

and if you can move it, then we just figured out what is wrong with your hummer. What did you use to flip it with?

 

Every TB I have cleaned I have been able to move the butterfly to clean around it.

Not sure what you are talking about egrogrart???

 

Me too. I can move the butterfly against some spring pressure and clean both sides. Just can't clean the whole TB as effectively as when I take it all the way off.

 

i used this vid to clean my TB on my envoy before and used as ref for cleaning H3, so happened that my # 6 plug got stolen on H3 .

 

TAINTER, I have no idea why I wrote that except I had just gotten back from a night out of a little partying. I don't know what the heck I was saying. I don't remember too well. lol. Maybe I thought he meant flip it all the way around or something. who knows. Anyway, sorry about that.

But yes, you should take it completely off to clean it properly. You cannot clean it like it should be cleaned with it on the vehicle. F1ipx, that is a good video and that is the proper way to do it.

 

How does a 300 hp car do 12's. it cant my bonneville had 305 and wouldnt. Sorry to get off topic. Lol

 

He said it was 320 hp, and modded, so it could be possible.

 

320whp would be close to 380 crank HP, and over 400lbft to the wheels but the dyno pulls were done on stock Cam, Since then there's been an addition of a mild cam and a liquid intercooler with FMHE. I ran a 12.3 @109 just missed my 110 sticker if I had to guess I'm in the 365 whp range as it currently sits

 

Ya closer to 400 sounds right. Lol. There fun cars tho all the 3.8s
