Default Air Intake / Throttle Body Cleaner?

What the hell? Why does this stuff have to be so complicated? What's the difference between:

Air Intake / Throttle Body Cleaner,

Carburetor / Throttle Body Cleaner,

and

Carburetor / Choke Cleaner?!!?

I plan on taking my TB off the car in the next couple of days and doing a thor-ough cleaning.

throttle bodies , especially tac drive by wire , can stall out by being sticky
I prefer GM spray top engine cleaner to clean throttle bodis
I use GM FI and upper engine cleaner is a pressurized injector cleaning pot to flush the injectors
it does make a difference

This thread isn't going well at all; I just wanted to know if carb cleaner is safe for throttle bodies; perhaps I should've worded the opening post simpler.

Don't use carb cleaner on a throttle body; did that back in 2000 and totally screwed up the throttle body .... get throttle body cleaner .... what's even more sensitive is the MAF sensor ...

Alright ... I know about the special CRC MAF cleaner, but I'm still confused about the throttle body cleaner because some cans say "Carb & Throttle Body Cleaner" and some cans (like the STP brand) say "Air Intake & Throttle Body Cleaner."

It seams like I heard somewhere that throttle bodies have a special clear finish on them that carb cleaner will take off!

The difference between carb/choke cleaner and throttle body cleaners initially is about $5. However, if you spray that 99 cent can of carb cleaner into a coated throttle body, it will cost you significantly more to replace the throttle body after you've damaged it.
I would opt for the air intake/throttle body cleaner. It is probably the weakest of the cleaners and less likely to damage something. All of the cleaners mentioned share the same basic gunk busting formula but, some may be less than full strength to prevent damaging coated throttle bodies and sensors. Read the label for more information. A little bit goes a long way and don't use anything abrasive that could scratch the throttle body.

I have cleaned throttle bodies and they don't give a lick of improved performance at all..
waste of time and money..
unless yours is so gunked up it's stuck or something I would just leave it alone.

The car's coming up on a 100K and I just thought that was one of the things you're supposed to do.

I cleaned my cars with 180K+ and don't find it necessary... sure, wiping the back of the plate make the rag black ...
but to clean it properly take out all the O-ring and shaft, plate, and put the whole thing in solvent will clean it properly basically a rebuid!

I think a check and adjustment TPS might be most effective thing at 100k.. if your car is fairly new don't do old school tricks like shooting cleaner up those smog nipple can screw up smog equipment..

If ain't broke, don't fix it ...

I prefer BG but, that's what we have on hand at work. CRC is good. I would stick to a known brand. If you're not experiencing drivability concerns, I would leave things alone. The frequent fuel injection flushes, decarbs, and other snake oil services sold at alot of places aren't really necessary as a maintenance item. In fact GM has a TSB out that basically says that if you're not experiencing drivability concerns don't clean of flush engine/fuel sytems. If your throttle plate isn't closing all the way or moving freely, it may need a cleaning. Otherwise, it's probably fine.

I have heard that the throttle body butterflies on some GM cars have a special coating that is ruined by standard carb-cleaner solvents.

Spend the money on throttle body cleaner and then go clean....

I'd go with CRC myself. I have never cleaned one but.....I have never had driveability issues that weren't connected to something else.

I use brake cleaner to clean MAFs and throttle bodies.

Or i take one off one of our wrecked donor cars.

I went ahead and got 2 cans of CRC Air Intake / Throttle Body cleaner today from Pep Boys; they were $3.99 each!

It's time to change out the coolant and since I have to drain the coolant before removing the TB anyway, I figured I might as well go ahead and do it now.
