Lumpy Cold Running

[72dudes]

Hi Guys,

 

2001 2.2 HDi 66k miles.

 

Just recently on the first start in the morning, the engine doesn't run completely smoothly. It's nowhere like as bad as as a misfire, just uneven running.

At idle, you can see the rev counter needle moving slightly. When driving there's the slightest judder for about 1 mile until the water temp goes out of the blue section.

 

Car is due a service any week now, any pointers please??

 

Thanks,

.

See what its like after the service. I take it theres no engine/service light on or no loss of power or extra fuel usage

Thanks Coastline. No, there's no engine/service light, no loss of power and fuel consumption is steady at an average of 44.3 MPG.

could be a sticky injector,fuel filter housing,air issues or possible sensor but thats just scaremongering at this stage. A drive round the block with a scanner on live data should bring it up. But at this stage i would mention it when your getting the service and not worry to much about it Cold start is controlled by temp sensor think there easy and cheap enough to possibly take a gamble and change it
