What do I all need to clean the throttle body? 2014 Tahoe

[iboughtatahoe23]

And do I have to reset the RPM? I don’t wanna have to do that… with like a computer.
I wanna know the whole procedure beginning to end.

For a 2014 Tahoe. Preferably from someone with a Third or 4th gen. Thanks.

you get some soft rags that are not "linty" and some throttle body cleaner.
remove the plastic intake, clean throttle body, put intake back on.
done
it's not complicated nor difficult
you dont need to disconnect the battery, nor the harness.
I have done it probably a hundred times over the years

Let’s getter done then. If you say that’s all it is. I’ll watch a few videos and report back how it goes.

if you want to do a deeper cleaning then remove the harness and unbolt the throttle body and clean both sides, but generally you can reach the inner butterfly with your fingers easily
if you unbolt it then depending on the age and etc you could end up needing a new gasket (maybe) they can get flattened

What gasket do I need ? Should I get it just for precaution? Don’t wanna be stuck without a vehicle.

Also, can’t see what post it was but I remember you saying that my catalytic converter might be clogged? And then you said that 900°F is a little high? I see some of swathdiver threads from last year saying that sometimes they reach 1600°F when accelerating which is normal ? Are you saying my idle temp for the cat converter is high?

I wouldn't worry about it unless you are specifically going to remove the throttle body.
if so any auto parts store should have a throttle body gasket/seal it's just a o-ring

my response was incorrect

500-800 is normal, with 800 deg being highway temps but should cool down fairly quickly at idle, 900 at idle is pretty high, 1600 would be off the charts

What your thoughts on this thread?

1600° was mentioned “normal” here

I guess I am wrong then I don't recall mine getting that high but maybe they did get a lot higher and then cooled down to 800 at idle, I know it is posted on here somewhere but the search function is not exactly spectacular

found when I was having issues

What did you do to your NNBS GMT900 Tahoe/Yukon Today?

i'm just over here like umm.... what's a good cat temp? lol, @80 mph mine are 1600deg's, idling for a bit there 7/800deg can't seem to find any definitive answer, can anyone with a tech2 take some data on there cat temps on the freeway and let me know what you are getting. just if you happen to...

So my converters are running 300°F when I used a IR laser temp gun. And then my OBD PID Bank for it says 1200°F and doesn’t really change. (I’ve only gotten up to 25mph looking at the temp tho) my buddy says 1200 is normal? Need @swathdiver to verify.

when I looked back my post's in 2019 I was getting over 1200deg, and getting poor mpg and one failed shortly after trying to figure out why i was getting significantly less gas mileage for no apparent reason

I don’t think I’m getting bad gas mpg. I get like 10-11

My buddy who was a service tech is telling me 1200° is normal for light trucks. And suv

Idling they can get up to or cool down to 700-800 degrees. I've hit near 1600 accelerating onto the highway. Then they cool down again. Don't remember the specific numbers but it's on here somewhere as we've talked about this a few times over the years. These are virtual numbers calculated by the computer.

Is there easy ways to check for clogged cat?

check temps or backpressure test, sometimes people pull the 02 sensor out and stick a camera in there

Ok and the cheapest way? What’s back flow test

Gee what camera? a noodle camera?
