Hi Everyone seem to have a couple of problems and wonder if they are related in some way, motor is a 1.9CDTI 54 plate estate.

1) Takes a while to start once it has started it runs fine other than what
appears to be an odd missfire when under no load, it will accelerate fine.

2) Driving along with no problem but then the EML comes on and it feels
like I have loss of power if I try to accelerate quickly it will pick up speed but
very slowly you can not feel the car pull. If I then pull over switch engine off
and then back on EML goes out and all appears to run normal again.

Any help would be greatly appreciated. Many thanks in advance
