general problems of the 2006 Mazda MAZDA3

Car continuingly shows evap dtcs including p0443 and p0446 as well as either too rich or too lean fuel mixture and and O2 sensor issue code. Both O2 sensors were replace previously. The main concern is dangerous and has already almost caused several accidents while the issue has occurred after driving from a stopped position. The issue is, when the vehicle stops at 0 mph, the normal idling rpm speed is around 750rpm. During stops longer than a second, the car will lower the idle rpms to about 500rpm and stay until the throttle is engaged. When the throttle is engaged the vehicle hesitates and comes close to stalling. The vehicle will not power the wheels above about 1000rpms when the throttle is fully depressed and the car will hesitate until the car starts to gradually move forward. This all is happening in the intersection. As the car gets to the intersection, the car starts to pick up to about 1000 to 1500rpm and only then will the car start to fully drive forward without relation to driver's forced depression of the throttle. Basically the vehicle is defiantly not going above 1500rpm until the vehicle is a certain ways forward. This is very dangerous and I have already had very close calls with a Dodge durango, a tractor trailer, an unidentified sedan, and a Toyota prius (of all the vehicles in the world). I was almost "t-boned" by a prius. This issue is I believe to be an issue with the fuel system or engine as this issue only really occurs when it is very very humid or hot out. Usually above 80 degrees with any humidity at all. Could be a vaporlock, although somewhat unusual for a fuel injected vehicle, it isn't impossible.
