I asked this in another thread, but will be good to post here too 
Last time (2 weeks ago) when i changed everythng, airfilter, oil, oil fileer, spark plugs, etc, the guy asked my to buy a Carborator cleaner, then he spread that in a hole ( i think is throttle body) the one that is covered by box that contain airfilter etc.. And he asked me to press the accelerater, and some dirt came out from the silencer.
Is that all for throttle body ? or i should do other thing to clean it up ? an other mechanic is asking for 800 RS to clean throttle body, i dont know if it is the same procedure or he will open it. Is it needed to do it ? or carborator cleaner is enough and rest is waste of money ?
Here I got an other question :
I went to computerized tunning center in G10, the guy is saying all is perfect in my car, except the Fuel filter, He explained me that when cars come from Japan they empty the petrol tanky, and when it arrive in paksitan they But the dirtiest OIl to just drive the car from ship to Loader. So it choak the Fuil Filter, pump. And it had to be cleaned out, and it is in BOX which is very fragile at the backside of car near seats. And it take 2-3 hours to do this Job. He is asking 1500 RS for this.
Dose anyone know about this ?
