Hi folks new to the forum
I have a mondeo 2008 2.0 tdci 140 70k
recent issue with rough running. The car will start first time and run well for about 4 or 5 secs then become lumpy. Like running on 3. When the engines up to temp it runs perfect no lag no smoke no reduce fuel consumption. No EML on no codes stored. Any one have any ideas

cheers
