Q: Intermittent starting issues (takes a couple of cranks to start) & throttle surge
间歇性的起始问题确实是随机的，并且已经取代了MAF，清洁了油门车身，燃油压力调节器，燃油滤清器和燃油泵。节气门激增也发生了，我还将电动机清洁剂（海炸木）放入燃料和曲轴箱中。这似乎有助于卡车如何闲置，但无法弄清楚为什么很难开始。
我的汽车有286345英里。
My car has an automatic transmission.

Hi there. From the description you have provided of your vehicle’s starting trouble and throttle surge, it looks like you have already tried replacing many parts on the car.Replacing parts without a diagnosis can be expensive and time consuming without a resolution.
It could be the intermittent no start and surge could be caused by afaulty fuel pump relay。这也可能是间歇性的曲轴位置传感器,throttle position sensor,凸轮轴位置传感器, powertrain control module, etc.
假设服务引擎很快/检查引擎灯不会亮起，这会使我相信计算机没有意识到故障。监视计算机参数可能有助于诊断。考虑到所有可能性，我建议您拥有您的车辆间歇性起始问题被诊断and repaired by a certified technician, such as one from YourMechanic, so that this can be repaired properly.
