PH2 172 high idle (2k)

[jarvis483]

Hello guys,
I've had a search and can't really find much information to help me, so hopefully a new thread might bring the advice I need.

Approximately 1 week ago I had my clio serviced. Oil, pollen, air filter changes, 4 new spark plugs, engine flush and all new oil.

Once this was completed I started the car and the idle was very high around 2k. After leaving the car idling for a few minutes, the idle returned to normal parameters. I know clio's have a rough idle but this is different I think. The car performs normally as it should but just idles high. I have since had all my belts and pulleys replaced by a reputable garage and the problem still persists.

Any advice would be greatly appreciated.

Air leak? Vac hose loose?

Cheers,

Martin

Yeah air leak or vac pipe, check all the inlet manifold bolts where the upper inlet bolts onto the lower as this has to be removed for the spark plugs to be changed.

Also check the map sensor and air temp is connected proper and that the vac pipe that goes to the acoustic valve and the brake servo is connected properly.

Thanks Dan, will check all of those things as soon as I get chance and report back any findings.

Yeah certainly sounds like one of then will be a likely cause as it's all been off.

Let us know how you get on

Did you find the cause for the high idle?

Mine was doing the same after a cambelt change. The garage reset the ecu using clip and all is well. In fact it's like a new car!! Might be worth removing your battery terminal to reset your ecu? Have your radio code handy though.
