吉普大切诺基1999年的问题

Well, I have a Jeep Grand Cherokee 1999, it is the 4.7 V8 4x4, I have two problems with her one is that in climbs that are not so inclined or so long, approximately 10 km, it heats up until I get almost three quarters and that because accelerating in a normal way to mild, the other problem that you have is that when you take the curves to the left and go at a normal speed, not so considerable, it stops accelerating even间歇性地停止加速两秒钟，加速了两秒钟，然后再加速加速，等等。一开始，我认为这是一个避免打滑或曲线的系统
