Have anyone done before?
Car hit almost 190km. Should I do throttlebody cleaning?
Or it is not a must to do so? By the way car is running fine. Any advice?
Take apart every bolt and screw and clean it, then oil it and put back better.
190km or 190k km?
If 190k km, I'd just do it. Clean the Maf sensor as well.
Another skool of tot is that if it ain't broken, don't fix it.

Sorry my bad. It is 190,000km.
Maybe I shall not do it, since my car is smooth and problem free.

Did before and regret
Maybe it’s poor workmanship, I’m not sure
