Hi guys,
I hope you and your lovely Clios are doing well.
While getting a performance map fine tuned for my Clio R27, I was told by the tuners (Ktec Racing) that my data logs show that the car is running with a high manifold pressure at idle. They asked me to check the cam timing.
I spoke to the Renault workshop in Dubai, they said its impossible for this to be due bad cam timing but are willing to check (diagnosis will take time and cost $$).
Google says it could be due to:
I recently installed a (slightly used) Ktec Air Intake kit on the car - I believe the issue is possibly due to a leak in the intake hose.
Has anybody dealt with this issue before?
Thank you.

Google says it could be due to:
- Leaking intake manifolds downstream of the throttle valve (e.g. due to defective intake manifold gaskets, hoses, etc.)
- Defective engine exhaust valves/hoses
- Leaking brake boosters
- Leakages in the vacuum system (e.g. vacuum-operated actuators, brake boosters, lines, etc.)
- Defective EGR valves (permanently open)
- Defective idling actuators
- Idling status of the engine is not recognised by the control unit (defective throttle potentiometer, throttle switch)
- Defective or dirty throttle valves
- Incorrect or faulty air filter inserts
- Carbon deposits or other blockages in the intake manifold
