Hello all, I wonder if anyone may be able to help me, please. Our A2 has begun to ' Hunt' when at tick over. The revs will rise, quite quickly to app 2000 then fall quite abruptly, it will then settle for a while before repeating the process. Otherwise starts and runs as normal, which is very good for 124,000 miles, and burning no oil between services. I've removed the air intake and cleaned, as best as one can without removing it entirely, with carb cleaner, the throttle flap housing, and poured some 'Wynn's' fuel system treatment in the tank, and for a while I thought I'd cured it, but after a few trips back it comes. Any ideas ?
Cheers.
Cheers.
