Cleaned my throttle body today

[marty1979]

Hi all. I was a bit bored today so I decided to have a play under the bonnet of the car. I completely removed the throttle body and cleaned up the inside with paint thinners. It looks brand new now, and it runs so much smoother, and the idle is much better. An interesting thing I noticed while I had it off was that there was oil pouring from the casing of the throttle position sensor. I opened it up and the thing was full of oil, so I cleaned that up too. My car has done about 160k so I would think anyone who's car's done over 100k would benefit from doing this, it feels great now, and was good fun.

Think there was a tip to drill a very small hole in the bmw emblem on the tps to let the oil out.
Sure someone who knows more will enlarge on this theory soon.

The improvements are probably down to a now working throttle body switch, rather than the TB cleaning!
