Rough cold start with misfire 2007 xc90 d5
Hi,
I have a 2007 xc90 d5 auto executive. When its been sat for several hours, overnight for example, it takes a few extra cranks to start, then it is rough/misfires for a few minutes. Engine, reversing and going forward seems jittery during the initial start up. After that, it starts fine and runs fine. Has anyone had this problem? Any ideas what it could be, or where to start in order to diagnose? Many thanks |
start with a new fuel filter and do a leak back on the injectors try to get the codes read with vida if possible and work from there. where abouts in Derbyshire are you.?:regular_smile:

It has just had a new fuel filter so 100% not that. My garage did a leak off test and said it was fine. But it does run OK when warm. It's just the initial few minutes. Cheers |
ok next check the swirl flap arm is connected and working then scan with vida to read live data to find out if the egr is working within parameters your just a bit far away for me to scan your car for faults and or codes..:regular_smile:

Xc90 rough idle
Hi. Did anything come of this thread? I've got the same issue, my Vida is pointing to glow plug signal. I'm guessing this is the reason? Swirl flaps were done but 40k miles ago.

try the easy one 1st
Glow plugs.. very easy to check/get at with a multimeter on low ohms (like 0-200 ohm) the plastic on the connectors also tend to fall apart, also clean up any contacts as they pass a fair current when energised, and crusty old connectors will greatly reduce the current flow.
