Hi I've got an st170 this morning when I was driving home I started to lose power,then when I tried to go up a hill I have zero power. Sounds like it is misfiring on tick over and when I tried to set off it was juking and didn't have much power. Can anyone come up with any ideas what it could be whats causing the problem?

Fuel pressure regulator??

Have heard by a mate that injectors are a common fault in the focus model, that's what I was told

That was my second thought. It's either not fuelling right or not sparking right. And the laters done so fuelling side of things

they are notorious for fuel pumps going wrong. have a garage check the pressure at the rail.
