Trawling the forum for help I suspect the EGR?
The car was left standing for 2-3 weeks over Christmas. Before hand it was OK... Occasional slight stutters but I put that down to me being over sensitive.
Now basically, I no power until 2700 RPM. On the motorway, I have to shift down to 4th to "accelerate" from 60-70. By the time the engine reaches 3000 RPM power is coming back but not as much as I am used to. In 6th gear the car will maintain speed but not accelerate. Overtaking is no longer an option but fuel consumption has improved.
No lamps on the dash...just the sound of Clarkson shouting COME ON!!!!
