问：当从驱动器转向反向时，发动机闲置粗糙，跳动在500至1200rpm之间；检查引擎灯
The engine seems fine most of the time but it idles rough and occasionally jumps between 500 and 1200 rpm when I shift to drive or reverse. When I throttle and it hits 4000 rpm, the 'Check Engine Light' starts flashing. Can you give me advice as to what to do to fix all of this?

You may have a couple of separate issues:
重负荷下的闪烁检查引擎灯很可能是点火系统失火。这可能是线圈包或磨损的火花塞。这些引擎以浏览线圈包而闻名，因此这是我的第一个猜测。
粗糙的闲置可能是相关的，但听起来更像真空泄漏或可能是空闲空气控制阀（IAC）故障。
The first step is to retrieve the diagnostic trouble codes for yourCheck Engine Lightwhich serve as a starting point for any further diagnosis. I suggest you have a trained professional, such as one from YourMechanic, diagnose your vehicle firsthand.
