Fuel Fail 44

Hello everyone,
Recently i have been having an issue with Fuel Fail 44 and the accompanying check engine light.
Namely, i have no symptoms besides the FF44 popping up as soon as the car warms up.
I have replaced the O2 sensor to no avail. occasionally if I am stationary when the car reaches operating temperatures there is a slight change in RPM, the needle goes from 650 to 750, then drops to 550, only to level out again at 650 and turn on the check engine all in a space of one or two seconds. From then on the car drives just as it usually would only with the FF44 check engine light on.
I have also noticed the increase in consumption expected for this condition.
Please let me know if you have any ideas as to what the problem might be, and thanks so much to everyone in advance!
Kindest regards,
Stefan
