Title: Rough running when cold?
Post by: johnte on March 05, 2008, 22:24:19
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??

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)

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).

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

Might be worth checking.
