Hello together, I hope someone can help me. Car is a Clio 3 BJ 2006 and the 1.6 16V with 88hp. If it’s temperatures above 15 degrees I have no problem, if it’s colder I have the following problem. I start the engine (runs always without problems), then it stops 1000 revolutions and with once it slams down to 500 revolutions, either it stutters around or goes out (if it goes out it jumps immediately again) then it swings or jerks while driving something, until e r was (so about 5 minutes drive) then it runs perfectly, even if I start the car in warm condition then it runs without any problems.The following I have already done. – new throttle valve – throttle valve cleaned. – New service (air filter, oil, spark plugs) – battery measured (12.6V when running 14.2V) I don’t know anymore, camshaft sensor can’t be, because it always starts without problems. Can it be a coolant sensor? Did anyone ever have the problem?
