问:我recenlty调节阀在我2009庞蒂亚克g5改变了窗口。在那之后,汽车开始体验降低发动机功率。切

必须改变窗口监管机构在我庞蒂亚克由于冰冷的窗户打破了。我点的是监管机构和安装我的朋友。第一个他安装是错误的,我从O ' reilly买下了它。他把旧回来检查工作。所以我们得到一个新的监管机构。他安装了新一,非常的顺利!汽车是在安装期间,死亡。所以我们必须跳。离开车后开始表演滑稽,开车慢。检查引擎灯,说发动机功率降低牵引/服务。 We checked the codes and the first one said P0013-Which was Cam Shaft sensor. We replaced that and the car seemed to be working. Then it died on me when I was at a light, but started back up. So we checked the codes again and the new codes were P0641and P0106. When looked up said ECM? Can I buy a used one and just have installed or does it have to be programmed and if so is it difficult? Also could it be something as simple as a battery?
