Revs dropping when on idle
Hi, I have Twingo 3 1.0 no turbo, the car has 32k on the clock. The engine revs started dropping when on idle, it feels like it is going to stall. It does stall when engine is started cold and I don't help it by speeding revs up. The car was ok before, the problem started after it was parked for a week. No issues driving the car, no warning lights, the only issue is revs on idle. Any thoughts on this please?
