Cars a 4x4 saph by the way. It was running standard leads and coil so i replaced with motorsport and grp A items, inc. uprated spark plugs. This seemed to slightly improve the misfire but still really bad under load. What would be the logical sequence by process of elimination??
Thanks guy's

Hello chris. Sorry to have jumped in on your thread, similar issues that we're havin. Can I just ask, how old is your fuel pump? Just been looking at some other posts. Apparently when some of the focus' suffer with a similar symptom, it's down to the pump and it's common. I know mine isn't new.
