Yeah done the maf, and it improved things, when cold i cant rev and it wont tickover, as it gets warmer it drives but wont tickover, when fully warm it runs like a dream and purrs on tickover. After work going home tickover is slightly lumpy for a few mins, but thats i t (Obviously not as cold as night) Once warm power is fine, fuel economy fine, no change on hils, cruises on the Mway at 70 -90 with no problems, can sit in traffic like today boiling away and no problems, so am guessing it must be the TB?
