Car died while driving on highway and sputters after a couple hot starts
First occurrence in December:
Second occurrence in February:
Third occurrence in February a couple of days later:
I took it to the dealership again and of course they couldn't duplicate the issue so I had them replace the pump anyway. Worst case scenario is yay I have a new fuel pump. It still does this after:
Ideas? The Mach has a 120,000 on it for what it's worth. I'm not sure if that sounds like an IAC or something fuel related like injectors or coils. Or maybe I should just throw all three at it. The bolded is the long story short Last edited by HamMach1; 04-04-2019 at 02:53 PM. |

Need to know what is the code that is presented. The FPRS could be the culprit.

Re: Car died while driving on highway and sputters after a couple hot starts
Was the first time when this happened (Dec) the only time it threw a code? Also, what exactly was that code?

Re: Car died while driving on highway and sputters after a couple hot starts
I feel like we've been left in suspense here.
Do I get a prize if I say it is the throttle body/TPS and get it right? _ |

Re: Car died while driving on highway and sputters after a couple hot starts
based on similar posts I would suspect the FPDM (under the kick panel in the trunk on the driver's side).

Re: Car died while driving on highway and sputters after a couple hot starts
Sorry guys. Every time I remember to check back on this thread is usually while I'm driving and then by the time I am home or at work I completely forget.
Latest example: Car was sat from Thursday afternoon to Monday morning and right after I started it the whole car was shaking and sounding really rough, until the RPM eventually dropped to a normal idle (which took much longer than usual... hovered at 1k for a good few minutes) Quote:

TPS and the CCRM. I'll add those to my list of things to check out when I have time. I suppose my first task is to retrieve that CE code. |

Sounds like the fuel pump going out to me...

Re: Car died while driving on highway and sputters after a couple hot starts
I think it might be the valve cover gaskets taking a dump on me. Spark plugs have a decent bit of oil on them. I imagine that's messing with the spark. At least that could explain the ignition/idle weirdness, but I'm not sure if that explains my random loss of throttle response/power while cruising at 70 in December

Re: Car died while driving on highway and sputters after a couple hot starts
I had some problems with stalling out under various conditions....changed O2 sensors and it went away.
I used my Torque App to troubleshoot a possible lazy O2, they were cheap and easy to swap and no issues since doing that about 5 years ago. |
