My first 172

[dafster1]

Hey,

Picking my first 172 up tommorow night off a guy called steve on here.

Has an idling problem a few other small bits. What is the most common thing with the idling. Its had the following done but still none the better he said:
Two 2nd hand throttle bodies an idle air contol valve( new from renault) and a new throttle cable from renault.

Is there something else that is common?

Thanks

Dafydd
