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?

 

did you find out the problem because my car is doing the same and it driving me crazy. any help would by very kind thanks

 

Could be, plugs, leads coil pack is the things I check first the plugs was knackered on my st170 and I had the same problem

 

well its had new plugs, leads, coil pack, fuel filter. and its still doing it.

 

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.
