I have a 1999 p38a with a 4.0 gems engine the engine will not idle smoothly, i have fitted new spark plugs and leads and i have checked the vacuum pipes for any splits in them, does any one have any ideas what it could be? Thanks Gareth.
 
Hi leads are ok i will check the idle control valve and change it if i need to .Thanks for the advice will let you know if it cures it. gareth
