My car isn't running like normal.
When it's idling at traffic lights etc. it 'chugs', and the rev counter doesn't rest in the same place like normal. It fluctuates a bit every five seconds or so.
Also, until the engine has warmed up fully and I'm approaching roundabouts etc, I put the clutch in to gear down, and it will cut out. This has always happened to it but only in very cold weather. It's been doing it in the last couple of weeks when its been far from cold.
Any ideas?
It's a ten year old mark 3 Golf, 1.4 injection, done 100,000 miles.
One of two things Mr Nottingham, either your throttle body is coked up (very common on that engine) and will need to be cleaned and 'adapted', or your coolant temperature sensor is telling the cars ecu (its brain!) that the engine is running hot, and to therefore 'weaken' the fuel / air mixture, when in actual fact the car is cold and needs a 'richer' mixture..
Either way its an inexpensive repair (if you know me!!

) but the smart money is on a dirty throttle body.
PM me if you need any advice
