Annoying zetec issue
Hi,
I am working on the tune and it is starting easily now- but when it warms up it seems to drop a cylinder (no4). Not all the time either...
I have done a compression test and it all seemed ok - not sure if a valve it sticking when it is warm being a silver top with hydraulic tappets...
Maybe it will sort itself out once I can take it for a proper drive and open it up???
It is slightly annoying any other suggestions would be welcome?
Thnaks
Frank

Knackered plugs? They foul up dead easy and can give the impression of one cylinder being down.

First stop would be Plug/s on a Zetec
Ford changed the gap iirc due to issues with them
