Hello I have just brought a 2006 connect tdci 90ps. When I test drive it all ran fine. Now when I start it up from cold it runs lumpy with misfire until warm. It’s had 2 new injectors by previous owner. Just a guess could the other 2 be gone?
With regards to egr valve does it need replacing or will a blank plate work as it’s the euro 3 engine. I do not get any lights on the dash. Also has very strong fumes coming from engine
