Rough running when cold?

(1/1)

johnte:
HELP!! Any ideas why a 4.6 P38 will run rough when cold?  it does this every morning when I start it, then after the first couple of hundred yards it's OK (It could be missfireing, but why :doh:)

Appart from this, no other probs - when it's warm it runs fine, temp gauge never goes higher than the middle and it doesn't use a drop of water??

ben_haynes:
have you had it serviced recently as we have been having a few probs with vehicles (extra cold weather we have been having) and a full service normally sorts them (Air Filter, Oil Filter, Fuel Filter(if fitted) and Spark plugs)

Range Rover Blues:
It should run rich when cold but I think mine has been running extra rich, it's often sulky especially if it's been stood and you can smell the fuel (I run the LSE on Optimax).

Skibum346:
Lumpy idle on our RRC LSE has been diagnosed as hole in the dizzie vacum advance diaphragm.

Might be worth checking.
