low idle?

[s-gx]

hi i just bought a 1.2 16v extreme clio 2005 plate last weekend. have no major faults from it as i am aware of but clutch bite point seems high but had a clio before and seems although it probably just the way they are but when the idle sits at around 500revs is this normal or is it quite low, i owned a polo before revs sat just over 1000s so just curious as every car is diferent. it doesnt seem to affect the driving of the car, ovbiously take off it slow but it is only a 1.2. it did have a service a month ago, was due a air filter but was wrong size so it never got changed. thinking about buying a wee cheap induction kit for it would this help the revs atall. also does it really make a difference buying a £20 induction kit aposed to a £75 one thanks guys in advance.

Would have thought it would be closer to 750 at idle time!

Was the Polo a 3-cylinder?

any ideas what the reason for it idling so low are like i say though still runs fine! it was a 1.2 16v

Any gumming around the edge of the butterfly in your throttle body? My old 1.6 had a similar issue with low idle at full closed as the oil vapour recirc sat next to the aperture. Not sure if the 1.2 is the same but easy enough to dismantle and check.

my 1.2 used to idle at around 400- 450, was horid but i never had any problems with it.
