TDCi owners help. What is r.p.m at idle

[tdci stevie]

Just want to know if theres a set r.p.m at idle on the 2.0 TDCi went at engine running temperature.... is it 750, 800 or 850 rpm

[mintalkin]

anything between 750 and 850 is normal.

Mine runs between 750-800 but has got like a hunting problem and the revs can drop as low as 716 rpm as recorded on my diagnostic live data record.

Im getting a few people say use premium fuel but which is best and will it cure my problem ?

Esso - B.P - Shell...?

And is supermarket fuel that bad as they say to be causing me these problems? ive heard that supermarket fuel has no detergent in it and it causes waxing on the injectors...?

And views/opions most welcome

The Haynes manual says the 115bhp is 800 rpm and the 130bhp at 750 rpm, hope that helps mate

Right have put a 500ml bottle of wynns injector cleaner in today when it was low fuel so its more concentrated, give it a blast up the motorway and put £20 of Shell extra diesel in, will see what happens (hopefully cures problem as so many suggest), will post findings
