问:我可以在传输问题和交流发电机麻烦?

你好,天呀,我有一个2000年吉普大切诺基有限4.7 lv8 4 x4 155000英里。最近她拖延了很多。下车后主要高速公路,然后坐在空转时红灯开车,但是如果我空闲在中性不太可能失速但将闲置的650 rpm和1300 rpm .....之间波动我们得到了一个引擎的代码p1391(我认为)但是它的“间歇性曲柄位置传感器或凸轮位置传感器。”I have replace both sensors twice with Mopar© sensors. It seems like this all started after I did a Seafoam© treatment straight into the brake booster. Sometimes I'll hear a rattling noise come from the engine area and my obd2 says I have a hydrolic pump failure. Also it feels like the jeep has hiccups in the front and rear wheels...(and also I get the death wobble but that's another story) My 4x4 doesn't work and my front drive shaft is taken out... Also, my headlights will go dim and back to normal while I'm parallel parking. Please help me!

我的车有155000英里。
我的车有一个自动变速器。
