so 2 years ago my buddys pickup with only 68k got a random misfire, went diagnosed and eventually blew up the engine. he got a loan from the bank and had a shop put a "new" engine in it with a 4 year warranty...
the same week he got the pickup back the same issue started. ive spent the last year helping him on and off replace random parts trying to get this thing fixed.
well take off from his house, drive maybe 4 miles, go thru a few intesections, drive maybe 10 minutes. randomly you will stop at an intersection and it will start running real rough, low idle, in drive. push the brake/gas, it gets better. put it in neutral and it pretty much goes away. stop at the next intersection and it may or may not do it, more often then not if you dont apply gas it will just die.
i have replaced the power steering pressure switch, fuel pump, filter, full tune up. ive unplugged pretty much every sensor i can think of, the injectors are plugged in, pretty sure i smelled the line on the fuel pressure regulator, sprayed starter fluid around, added an extra 5 ft lbs tq to the intake. probably forgetting some stuff.
it has been back to the shop that swapped the engine several times, as well as the ford dealership. in fact the pickup basicaly lives there now, they cant seem to figure it out. and say they cant do live streaming.
any idears? google search shows a bunch of these threads on the f150 forums.
