won't rev, lumpy tick over
« on: 07 December 2014, 15:34:29 »
Hi, I have a 2.2dti, its hard to start and when it does, tick over is lumpy and when I try to rev it goes to about 2000rpm the engine management light comes on, no fault codes showing, I have replaced the injectors and cross overs but no change, please help.
