Technical JTD 105 Lumpy Running

[stevec]

I've got a marea JTD 105 with 108K.

In the last month or so it's started running a little unevenly when just driving at a constant speed at around 1400-1900 revs. Just jibs a little nothing major but seems to be slowly getting worse.

It was remapped about 50K miles ago and still blasts up the hills like it did before, although I've noticed less smoke when doing so.

Has anyone any ideas?

Oh yeah and does anyone know how much it generally costs to change a clutch on these?

Regards

Steve

get a diagnostic and see if there is any fault codes stored. Also check the EGR valve, you could disable it and see if it makes any difference. Clutch is a pig of a job because the subframe needs to be dropped, so expect lots of labour..
