Hey guys, got an interesting one for you..
I've been having some issues with my '13 Pursuit with the 5.7l while driving uphill.
Basically what's happening is the engine totally loses power but stays running. The power loss usually comes in 3 parts. First is the complete loss of acceleration lasting for about 4-7 seconds. (Scan tool confirms that throttle position falls to zero as this happens)
2nd is a short burst of acceleration lasting about 1/2 to 1 second.
3rd is another fall to zero throttle. This one ranges in duration from about 5 seconds on up to 10 seconds. After this it's back to normal. The times at which this happens is totally unpredictable..
It has happened when the engine is hot, cold, full tank, near empty tank.. I've tried a few bottles of Heet over the course of a few fillups and nothing has helped.
There are no DTCs activating when this happens other than an occasional P0741 that's probably more likely related to this and not the actual cause.
I've been hearing all kinds of stuff that it could be from a fuel pressure regulator or the fuel filter and even the throttle body..
Any help or advice is much appreciated.
Thanks
