knocking

Hello friends, I use the 1.4 gasoline trendy model 207 I do not squeeze my foot off the gas when I put the 1st gear in the second gear, although I take my foot off the gas, the car is yelling when I press the clutch, this may be why it is like I have achieved the idle gas, this may be the reason that it knocked when I shift up, can help the mechanics. There is no trust in Izmir, can you tell if anyone knows this job?

Probably the problem is that cleaning the throttle will improve self-gas. The knock event may be due to the gearbox clutch and engine clutches.

There may be a problem with the gas potentiometer. but first the butterfly needs to be cleaned.

I hope it is not a very costly thing.
