lol u don't on the MAF but for my TB I used WD-40
I just remember on my old Audi whenever I cleaned out my MAF i had to put it in a plastic bag and fill it with something like isopropolyne (sp) and flush the whole MAF that way, then let it dry and install.
But this MAF spray seems to be the same thing, just easier to do.

That was not very wise. It might have cleaned off the gunk, but it's far from optimal. A TB cleaner like the CRC stuff I mentioned is a solvent that helps clean off the dirt and doesn't leave a deposit behind. WD-40 is not a solvent at all and not only leaves behind a deposit, that deposit can actually help attract the gunk you were trying to remove in the first place. Using WD-40 to clean anything is a bad idea, let alone something as sensitive as a throttle body.
Defratos, you've been here a while and should know better. Tsk, tsk.

Cleaning TB is a must if you're living in the GCC, i cleaned mine today, and wow i really felt a difference, the car feels more smoother, better throttle response, rpm is pretty smooth, you really should clean them, you won't believe how dirty they are when i opened them.
I used WD-40, it cleans and lubricate, use the nosel to spray the shaft so that all the dirt inside the shaft that you can't reach well come out with the nosel spray pressure.
After i finished i turned the car on and the rpm jumped to 2500 and didn't drop down until i pressed the gas pedel, the it stuck at 1500 rpm, so i let the car to reach normal operating tempreture and i floored it for 2 runs, turn the car off, let it cool down, i started the car again, and the rpm was normal.

great !
but will (WD-40) do harm on the TB's speciall coating ?
WD-40 is kinda strong chemical , so it's better to use a special TB cleaner, i believe .
what do u think ?!
second . . should i disconnect the negative terminal before i do the cleaning ?
thank you Q8 for the important/useful topic

What special coating? we've been using fuel, WD-40 and carburetor cleaner age's ago, nothing happened to any of the TB we cleaned, as long as you use something that would lubericate the shaft you should be fine.
Go ahead guys, clean your TB and tell how much dirt and sludge you found in there, i was shocked for the amount of dirt i found after removing the TB, i've never seen anything like it before, and BTW it can be done without removing the TB, you can use a towel soaked in whatever clean you want to use and push the flap with your finger and clean it, don't worry about anything, i didn't d/c the battery, i didn't remove any cable or hose, and i pushed the flap wide open with my finger and cleaned it.

Nothing seemed wrong with using WD-40, got the dirt out pretty good, and haven't had any problems until now, conclusion.......It's safe to use and works well, especially for those of us who don't have a decent shop to buy all these goodies you guys have on offer

I've been using WD-40 to clean TB's for a long time, never had a problem with it, of course i use a towel to make sure there is nothing left on the TB, no problem at all, i'm talking about my self, i never knew there is a special TB cleaner, but the reason why i used WD-40 is the lubrication it add's to the TB beside cleaning it.

i just did this, it wasnt too hard however i was using an allan key ratchet type attatchment nd it kept getting stuck on the bolts which was unbelievably annoying also putting the intakes back in was a minor pain... all in all it was an ok task.
I didn't find as much dirt as u guys claim on the driver side body but on the passanger it was literally dripping off....i think they might have changed my driver side one for something not to long ago, anyway i havnt driven the car yet but heres hoping it stops my wierd idle

no. Coupes don't get the orange rubber one. That's the one you guys get on new gen sedans and other VQ engines equipped with 2 TBs.
We get a metal black one with a little groove in it. So when you tighten the TB bolts, groove flattens out a little and seals the TB.
And gasket replacement alone did not take away my light, I had to do Idle air learning procedure.
