Any good guide for cleaning the throttle body please?
After you have removed the air pipe and box where the air filter comes, there are 4 screws holding the Throttle body. In my case, they were really stuck so had to use little bit of the force to make them free. Once you remove the throttle body, use a little bit more of paper towel and insert it into the hole on engine side to protect of having something to fall inside. Be careful not to push it to deep cause it will be a pain to take the towel out.
Now, when u have a throttle body free, spray one side with the break cleaner, leave it for a bit and wipe it with the paper towel. If it has gotten to dry (break cleaner dry really fast), spray it once again and wipe it off. (in my case, it was really dirty and dark). Be careful not to push the '*ear'. Just wipe it gently over its surface. I was little bit scared not to break the 'ear' so didn't play around it too much.
*the thing which closes and opens to let/stop air coming into the engine.
So far, I can tell car works better. Have driven it for a week after I changed the plugs and cleaned up the throttle body and when car is in idle, RPMs are stable at 800 (don't jump from 400-800 like before).
Also what I have notice better, so far when engine is warm, car hasn't shoot off, which was my No1 issue.
Good luck in cleaning, let us know how yours went.
