Hello, i have just fitted a new standard ford cam, hydrolic lifters ,rocker arms and valve stem oil seals. to my s2 and am having trouble getting the car to idle smoothly, when i start the car some times i have to push down the metering flap down to get it to start, it sounds fine when the revs are held at about 2 thousand revs but you have to slowly let go of the metering flap slowly then it will idle but just quite roughly. Also i have started the car like this about 6 times but havent bedded in the cam yet as i wanted to sort the idleing problem first, will it have done my cam any harm and what is the best way to bed it in.
I cant find any airleaks or anything and have put new boost hoses on it but stil sounds like it running on 3 cylinders. really anoying now.
Any ideas
