lipso Posted August 24, 2013 Share Posted August 24, 2013 I have an 04 fusion 1.4tdci with 117k - when driving roughly between 45 to 50mph in 5th gear uner light acceleration there is a noticeable slight judder - it stops if I decelerate or accelerate harder.Also noticeable in other gears when driving fairly slowly and with minimal acceleration. Otherwise the car drives fine - it feels a bit similar to 'hunting' in a petrol car Have read a few posts about similar problem but no solutions Quote Link to comment Share on other sites More sharing options...
Gombal Posted August 24, 2013 Share Posted August 24, 2013 Still have a fully functional EGR? Used to have it but since i blocked the EGR valve it is gone (still have a 6 mm hole in the plate, gonna replace it with a full plate). I can now accelerate from idle engine speed without any hesitation or judder. Drives a lot nicer this way. Think it's because the engine gets exhaust gasses through the EGR when on partial load and doesn't like it. Same as we would breath in a bag so we would breath in "used" air with just a little hole for fresh air, we wouldn't like it either. Quote Link to comment Share on other sites More sharing options...
