idling speed on 99 1.2 8v

[stevewright]

my clio seems to idle very very low (about 750 rpm) almost to the point of stalling (u can feel it shudders slightly)


is it easy to adjust the idling speed?

i read it was a prob on 16vs, but didnt see mention of 8 v?

Thats what they should idle at, but they do seem to shudder abit, mines been like that for 3 years and not stalled once! 1.4 8v btw

yeah, it always idled quite low, but never stuttered quite as much as it does now

is it simple matter of twisting a knob or sumthing?

all it needs is a few more revs to be happy

my 1.2 16v idles at about 600rpm and drops to 500rpm if i put the heated rear window on lol not stalled yet

No as its controlled by the ecu.

ISCV could need a clean.

wots iscv?

how do garages adjust it for mot etc?

They can't adjust it.

Its basically just a small valve on the throttle body that opens to allow enough air in for the engine to idle but over time they get cogged with s**t (i.e oil from the the breather return) and cause similar problems to what your describing.

Solution is to take it off and spray carb cleaner or similar through it or else buy a new one. Your car will have a DIET engine inwhich case find the throttle body and you'll see a small black cylinder (like the size of a C type battery) - this is it.

Oh, if you can't do that a cheats way is to keep the thottle butteryfly open a little all the time...to do this, find the throttle body again and you'll see a small bolt which can be screwed in/out and force making the butterfly stay open...it'll be fairly obvious. Try option one first though.
