Hello just wondering if anyone can help me sort this problem out. i recently brought a focus 2.0 TDCI 2006 Ghia, now it was running fine until one day i drove as normal and going into 3rd gear seemed to lack power and decelerate, happens in 2nd 3rd and 4th, i have sometimes have low power when starting off from a stand still and end up stalling it, now i can turn off the engine, re start it and will be fine for a period before it restarts. when i say period just getting further down the road then it restarts.
Now i instantly thought EGR Valve so have replaced egr and housing.
next thinking of doing air and fuel filter next to eliminate those before i go onto DPF if i have one.
Had a 16 pin reader by garage came up as okey
Any help much apprciated
