Continental GT Judders & Jerks when cold
So over the last few months its been getting worse.
When you start the engine from cold (i.e everything is the same as ambient temperature), it idles and accelerates fine, but then when holding a steady speed and light throttle, the car judders like I and playing with the accelerator.
It hard to describe, it's like I am putting the throttle on and off really quickly. If I floor it, or let off completely the car is smooth as silk. Not noticed any dip in performance either.
After a couple of miles, it returns to normal and the juddering jerkiness goes away until the next day.
Any ideas? Car is regularly serviced by Bentley, and no fault codes present.

There can be a number of factors that create the symptoms you mention. Do you have any computer diagnostic info? Also, can you provide data on age of vehicle, mileage etc.?

Check Mass air flow sensors and fuel pumps it has primary and secondary
one of them just starts the car and only runs for 20 sec or so then 2nd one will kick in also under hard acceleration, i replaced both of mines and th e diffecence was night and day.
