I have a 2000 honda accord 4 cylinder automatic. at first the car will be driving normally, but when i hit a big right curve the problem starts after the curve. my rpm will not go pass 4000 rpm. It will stall and shake at 4000 rpm and lose speed. i dont know what the problem is. But after turning my engine on and off again the car will drive normally. could it be an electrical problem? transmission?
