Just wondering if anyone else out has had similar issues with a rough running HDi.
The issue has been with the car for the last 5000 odd miles but its fairly intermittant. It's coming to the point of annoyance so just looking for a solution.
Drives fine under load and cruising, did 380 miles this weekend without issue apart from only when waiting in traffic for around 10 minutes the engine would not idle smoothly
at all. Ranging between 600rpm to 1200rpm this is particularly the worse I've had it and what seemed to be different was the coolant temperature was up to 90* (normally sits around the 80* mark - was hot out) The throttle becomes light for the first 10% and as if you have no feel over it, as soon as you give it around 30% on the pedal and raise the revs its fine and will hold a constant rpm.
It did it previously (months ago) when I happened to leave it ticking over for around 10 minutes, I could hear it hunting, and running rough but it never cut out. When I came to drive away, it left a chronic cloud of blue smoke but then cleared and carried on fine.
The car has been fully serviced, and the pump was swapped for a good unit from another HDi which I drove for a couple months that didn't have the hunting issue, also put a bit two stroke through and couple tanks of V power derv.
Annoyingly I could drive the car for a week and its fine, else it can play up a couple days in a row.
My guess is injectors, ideally I need to leave the motor to get up to a higher temp to see if it plays up and hook planet into it.
Just seeing if anyone else has seen or experienced anything like it before.
Cheers for reading
