When starting with engine stone cold it starts first time but after 15 to 30 seconds it labours and stops.
If I turn the key straight away it won't fire for about 20 seconds then when it does start I have to try and keep it going until the engine gets a bit of heat in it then it's fine and runs perfect.I always thought that it reminded me of an older car that has a choke and you switch it off too soon so the mixture isn't rich enough but I was told by an engine tuning firm that it's deposits built up on a valve stem and thats why it starts ok but as the valve stem expands with heatthe deposits make it stick and the engine labours and stops. Then after the engine warms a bit and the valve hole expands it frees the valve and the engine operates normal once again until the next cold start. He said it would cost £500 to remove the cylender head, remove the valves and clean them.
It's a lot of money I can't aford. Was their diagnosis correct?
have the same problem?
