206 d (1.9 xud) feeling rough at light throttle

[BGB autosport]

I have a 206d, ever since it got it 20+k miles ago its felt alittle rough almost juddery at light throttle upto about 25% throttle. Recently its gotten worse but im not sure as to what it could be, any ideas.

Air leak?

I will give it a good check over, one thing i had not thought of. Today it felt generally down on power so the problem may be becoming more obvious.

If it is a DW8 engine have had a few with problems like yours with the egr valve located on the inlet manifold,I have made sure it is closed then disconnected the vacuum pipe and blocked the end off

Yes I had one once drawing air into the fuel via a faulty fuel heater. It ran but was down on power and lumpy etc....
