About time for a throttle body clean?

[AdamDavis]

Hi all,

I have a 2007 Toyota Yaris 1.4 Diesel that has done 183,000 miles and was wondering if it is about time that I cleaned the throttle body with my next service on the car. I have owned the car for 2 years, 40,000 miles and have never touched the throttle body. The closest I have got is cleaning the MAF sensor which was a bit dirty.

The car does not have a rough idle but it does feel sluggish, however I put that down to it being a diesel, which may or may not be correct.

So I was just wondering if people think it's worth doing and if so, is there any relearn procedure for Toyota's? Or will a good drive sort it out afterwards?

Thank

Ps. I have cleaned a throttle body before, so I am familiar with the process. Just not on my car.
