Hi

My 106 is still running rough for about 10 minutes, until it warms up.

I have done the following -

Changed the fuel filter, also checked for no bubbles in line to pump
Oil & filter change
Put Forte diesel fuel treatment in the tank for a few hundred miles
Had the pump timing checked & new cambelt
Had the valve clearances checked
Checked the cold start mechanism from the water pipe works fine
New glow plugs
Checked the glow plug relay

It was doing it before I had all these done and I just cannot
understand why it’s still running rough.
When it’s warm it runs perfect, full power, no missing, very
economical and not rattly or smokey.

Any ideas would be gretefully appreciated!

Thanks in advance  

Andy
