Whats correct engine ide speed for 2.5 CRD
 
I think my idle engine speed is set too high. Its close to 1000rpm and when i drive off and put the gear into 2 and in slow traffici have to continuously brake as the car moves too quickly without me even touching the accelerator. Like the revs are rather high for that gear if i make sense :mad:

How many revs should it do in idle/neutral

Cheers

Can't find the exact figure, but it should be between 790 and 870 RPM (worked out from some of the requirements of diagnostic tests)

Regards
Richard

Thanks. i will try get my exact one tonight. is it possble that idle has been adjusted higher than normal and if thats the case can that cause over fueling at start up?

The idle speed can't really be adjusted, it's a software function and not a screw like in the old days.

Not sure if it could be caused by the accelerator pedal not fully returning to rest though.

My 2002 2.5CRD runs idle at ~900

- why 2 ?
- your RPM is correct for an automatic

I remember I have a shot of my idle rev (also manual) :)
BTW I also used had the habit to drive away in gear 2 with manual diesel engines but I found it was not the proper way with the heavy weight of the Voyager. With heavy cars like this you really need to use the 1st gear, especially with a little cargo in it.

Noted. I will desist from starting off in 2nd use 1st. I wish this lovely car was an automatic
