Hi, it would seem I have a problem with my car. The engine is Z16XEP and I'm lucky if I'm to get 200 Miles per full tank.
I do approximately 10-15 miles per day and don't use motorways. Only really use it for work and back. The car since owning it had code P1113 which has something to do with the twinport flap's positioning sensor.
Made a thread about it ages ago (http://www.astraownersclub.com/vb/sh...d.php?t=280267)
Anyway, what could be the cause of my high fuel consumption? I've been told by a Ex-VX employee that the flap's sensor wouldn't be the cause of this particular problem.
