i got a s5 vert a couple of things dont work but all in all its a clean solid car the car wont rev over 2 grand so i figured out if i unplug the tps sensors it runs other than loud shotgun backfire every so often. im guessing the the sensors r bad is that right? the other thing is in third, forth and fith gear under full load the car dosent go through t red line smooth it kinda jumps... im guessing its the cats stoped up any sugestons.....
