Erratic idle speed

Hi all,
My V8 seems to have developed and erratic idle speed. It dosnt fluctuate as such, but when i stop at traffic lights it quite often has a higher than usual idle speed. It is exactly the same on gas or petrol. As it is not a constant fault, im guesing that the carb / throttle linkages are in need of some lubrication.
If this is the case can i use ordinary motor oil or does it need to be somthing special?
TIA, Tom.

put your foot under the pedel and lift it up to see if it settles back down to normal

Martains got it. U can also check that the plungers arent sticking in the barrels if u have SUs. Might make a difference.

I tried the lifting up of the peadle, no change.
I will be checking the plungers as i have SUs, although they were fine when i checked for restrictors.
