I have been looking intensely in this forum for hours to see if there are pictures or videos of how to remove the throttle body from the engine and clean up details and nothing so far. I have a M3 S automatic, and each time I am on a red light the engine idles rough taking the rpm to below 500 almost shutting the engine off. If anyone in this forum knows or have any links to how to remove and clean the TB with pics please let me know. I already tried to clean it with carb and choke cleaner and a tooth brush but no change.
Thanks
:mj:

Here is a pic of the throttle body:



As you can see, there are 3 bolts that hold it on. Be sure to disconnect the TB connector prior to removing the bolts. Also, there is a gasket, so be sure to go out and get a new one before you take it off. Most of the time you don't have to, but I would just to be safe.

Cleaning the throttle body on the car with carb cleaner should remedy any problems originating from there. The problem is, the TB is electronic and unless the butterfly is sticking or there is visible buildup on the TB, then cleaning it probably won't help. Are you throwing any check engine lights? If so, what are the codes?

There seems to be quite a few problems with the Purge Valve Solenoids and they are getting the blame for problems like these.

Here is the Technical Service Bulletin for the Purge Valve Solenoid if you want to try and test it yourself. I'm not saying that's the problem, but its a good start:

Do you have an aftermarket intake? If so, check and clean your Mass Airflow sensor with some MAF cleaner or something comparable. Sometimes oily K&N style filters can gum-up the MAF sensor. The wires and pins on the MAF plug are also sensitive, so you could inspect those for corrosion and/or damage.

you can clean the TB w/o removing it if you don't mind staying bent over for a while, just remove the intake hose, find something that will hold the butterfly open (fingers work but something else might work better) just make sure you don't drop it down inside the engine (bad) and spray it with TB cleaner, use an old toothbrush and scrub it good all around, etc., let it dry, put it all back together and start it up, can also try cleaning the maf sensor with some maf cleaner available at parts stores, look for soem how to's on this site for guidance and tips.
