I recently noticed my car under performing. I have a 2009 1.8TDCi Focus Zetec.
Upon checking the engine bay I noticed a badly burnt wire and connector.
The car runs as it should when cold, when it gets up to temperature it stutters and large loss of power after 2200rpm. Also a larger than normal cloud of smoke puffs out of the exhaust when it is stuttering.
When it is warm the car starts ok and drives fine under 2200rpm.
Another point when the car starts stuttering I can hear what sounds like a boost leak (whoosh).
I have checked all boost pipes and these are all ok, I checked for fault codes and a "Low Fuel Pressure Fault" was showing. Also I have noticed an increase in fuel consumption although the MFD displays normal MPG.
I know I'm going to have to replace the glow plug loom but would this resolve the stuttering issue.
Any help will be greatly appreciated.
