Well just when I though all was going well with the Z, it 
decides to be naughty today. Car has been sat for two weeks, so thought I would take a break from BBC News updates and go for a drive.
The car started fine, and initially drove fine, but once it was almost up to temp, the idle seemed to be hinting a little bit, with some very quite popping noises from the back. If I turn the AC off the revs drop to approx 500rpm and the idle seems quite rough. If I blip the throttle in this state, it almost cuts out. No lights on the dash or codes available to work with. Anybody have any ideas? The car ran perfectly the last time it was out, but did not seem a happy girl today
