smcqis Posted October 13, 2011 Share Posted October 13, 2011 I drive a 2004 diesel fiesta with near 100k miles on it. Over the past week the car has been slighly jerking (not all the time) at say if i was travelling in 5th gear at 60mph sometimes the rev needle would slighly flicker and i would feel it in the car. Any ideas what could be the problem? Im guna fill up today and put some injector cleaner in to fuel hope it helps Quote Link to comment Share on other sites More sharing options...
orcomma Posted October 13, 2011 Share Posted October 13, 2011 has it had the fuel filter replaced yet? Quote Link to comment Share on other sites More sharing options...
mintalkin Posted October 13, 2011 Share Posted October 13, 2011 also check for leaks at the injectors as the fiesta are known for the injector seals going. Quote Link to comment Share on other sites More sharing options...
