I don't think the power delivery is weird at all. Guessing you have an auto. If you try flog it in drive then of the course the car is going to get confused as to which gear etc you want, but if you drive in perf mode I found the throttle response amazing and the power is delivered quite linear considering its turboed. Also the traction control is upgraded big time from B series. Have a drive of a B series if you can, my traction control was rubbish but in the fg it just cuts the power down a bit rather than altogether so your still accelerating but hooking up the tyres And the idle issue could be because something needs replacing; plugs, coils etc. Depends on how many kms you got, again mine idles pretty good although is getting new plugs etc when it goes in for a tune Not to try completely discredit everything you said but these cars are amazing value for money and I don't think these things are 'bad' especially when you drive other cars to compare it too
