Verify the intake valves/ports have been cleaned with extra attention on the port near the PVC hose.Thanks for the reply. I'll give an update. I took it to the dealer and they recommended new plugs and coils. They wanted $1500 for it so I bought OEM parts on Amazon for $250 and replaced it myself. This did not fix the issue. It still feels like an engine miss when slowly accelerating. I also changed 5 quarts on the transmission with a drain and fill but I don't think that helped anything either. It sucks because the dealership misdiagnosed it and because I din't spend the $1500 with them I really can't hold them accountable either.
Mine did same. I cleaned MAP and problem solved.Our 2017 Explorer 3.5 twin-turbo is experiencing a surge and hesitation at the beginning of a slow take off, or a rolling take off. There are no codes and the dealer has replaced the purge valve. It feels as though you are barely depressing the accelerator and letting off. Any ideas?
They have 300K+ of the same issue. Your only option is to find a good Tech or file under the Lemon Law if it is under Warranty. I have heard but not verified things as simple as spark plug gaps. No one checks these before installing, sometimes even when replacing!Frustrated
Do you mind if I ask which dealer is working on your vehicle? Mine is at Hardy Family Ford in Dallas GA. I have had my vehicle there numerous times and they've never been able to duplicate it. And "Ford" is unaware of any other vehicles with this same issue. They also said the way the Hotline works if any other dealer had this issue they would get a hit! This last time, Nov 4th I was able to get it to duplicate the issue with the Service Manager in my vehicle. He said they would get to work and get it solved. They have communicated with the "Hot Line" and a Field Service Engineer came to the dealer, checked another "like" vehicle {which did the SAME thing} and they determined that it was NORMAL OPERATION! I have driven 4 of these vehicles, purposefully, and none of them did it.
Now, Ford customer service says there's nothing else to be done since the Field Service Engineer has made their determination. They now want me to take it to another dealer for a second opinion! Seriously?
Just purchased a ‘13 with approx. 130,000 miles and am experiencing the exact same issue. When slowly accelerating between 25 and 40mph there’s a surge and pause. I initially thought transmission, then plugs and coils. I’ve also read it could be the throttle body or the timing chain. I’m hesitant to take it to the dealer as they charge $150 just to diagnose and it doesn’t appear that anyone has actually had the correct diagnosis yet. I’d be interested to hear what has happened both long and short them to those that have posted in this thread.
Any luck with this problem. I have 2013 also doing the bogging down chugging thing around 25 miles on the highway no problem. Dealer can’t figure it out and have already charged me 1100.00 dollars.
