Ok then I would start thinking about fuel filters(last time changed?) the in-tank may be blocked, fuel pump could be a possiblilty, not sure why on corners though, maybe be a loose wire/bad connection.
its got a maf, its a door type depending how much air is flowing through depends how far the flap is open... why would a map do that while turning?? Thats why i asked is it at a certain rpm, because my camry went spastic until i changed the map sensor at 4k rpm
Braking heat is dissipated through a variety of methods, from air hitting the rotor itself right through to the wheels. I prefer to give the rotors and calipers a hit with high temp black, just to take attention away from them.
