    Intermittent shut down issue

    Unfortunately there is no consistency in when, where, how, or what the circumstances are when it happens. Hot, cold, idle, highway speeds, it is completely random. This weekend in fact, not that I have stopped driving it completely, I stared it up to keep the battery charged and the fluids...

    Been getting the same codes from the jump P2135 P1515 P0120. The throttle body I changed due to a roughness to the operation by hand I read online of those having and issue with that.

    Reduced Engine Power, reducing my sanity

    I've been dealing with this issues for a year and a half. I have a gut feeling it might be the ECM. Another wierd thing I have noticed is the driver seat forward and backward control is backwards now. My setting are on driver 2 my wife's settings still operate normally. I am so over electronics...

    The codes it popped up this morning in are P0120 P1515 and P2135. Considering they are all throttle related and I have replaced both the throttle body with sensor and the accelerator position sensor I have been thinking maybe I should replace the pig tail for the throttle body. I have inspected...
