问:汽车的汽油用完了,多个维修了

借我的车给一个相对时,他跑它完全气体,自然不会开始。我去帮助和添加汽油。最终我们可以得到它开始,但是现在发动机运行在可怕的状况。懒散,整个汽车震动。车辆没有权力。我甚至不能上升一档30度斜坡。另外,排气现在似乎比以前响。有可能是垃圾吸入燃油系统,所以我添加了一些良好的燃油喷射清洁和填满与天然气汽车;然后开车大约10英里。然而,它没有帮助; it still badly performs the same as before. The check engine light now flashes. I had a local auto store do a test and it showed a misfire. Another problem is that the catalytic converter glows red hot. There is probably excess gas getting to the converter, but I do not know where to start if that is a problem. The car is running, so I assume it is not the fuel pump causing a problem. I purchased a new fuel filter, but first I am waiting to see if the injection cleaner was any help at all. I’m also considering that it might be the coils, spark plugs, spark wires, or clogged fuel injectors. I can generally do most car repairs, except for motor-related repairs like pistons, fuel injectors, timing chains, etc. Would you please give me your advice if you think there are things that I can do myself to fix these problems.
