have had new chains fitted today balance and cam but missfiring still , can not work out why it runs fine untill you turn it off and restart just on the point when the engine starts to cool it starts to play up have been told this could be due to sticking lifters but not convinced if it was a older car you would swear it was damp in the cap . your help is most needed as i am runing out of ideas and money on what to do next no eml light on and no fault codes showing only done 75000 miles put a new coil pack on some time ago do not want to take to the main dealers as i am sure some one on here will be able to figure out whats wrong . please help
