问：加速时零星的功率损失
Issue started Thursday June 2nd, 2016. Was accelerating from being stopped at a stop sign and noticed it did not have the initial power from the engine like it normally does. Pressing down on the accelerator it would gradually get up to speed and then once it did, it kept the power and speed. Got to where I was going. Had it shut off for about 3 and half hours. Then started out again and noticed this time it had all the power and acceleration like it normally does but only to lose it again after I had to turn around, go back, this time only put it in park and keeping it running then back into drive and go and have slow acceleration and no power once more.
它的4.7L V-8。自动反式和AWD/4WD。
My car has an automatic transmission.
你好。这可能是由许多事情引起的。如果检查引擎灯亮起，那么我通常会从scanning the computer for codes。如果有代码，那么它可能会使我了解正在发生的事情。
如果不是这样，我通常会监视传感器的信号，以查看是否有故障。如果他们也很好，那么催化转化器needs to be checked for clogging and the fuel pressure must be checked as the泵可能失败导致低燃油压力。
据您所说，听起来燃油泵可能正在出门。如果您打算对此进行查看，请考虑可以来您家或办公室的认证技工的帮助诊断您失电的损失。
