    2017 Expedition - Jerky acceleration, misfires (P304, P300, P305)

    Okay, reporting back. I have now been driving the Expedition for a week and I am confident it's been resolved, at least the bulk of the misfires, as the CEL is no longer coming on or flashing when accelerating. It is running great now! I went back and pulled #4 plug and coil and did a...

    2017 Expedition - Jerky acceleration, misfires (P304, P300, P305)

    Appreciate the comments. It sounds like I need to check the plugs and coils again. I guess I think it unlikely to be the spark plug or coil on cylinder 4 where the issue is occurring (P304 code), since I just replaced all the plugs and swapped cylinder 4 and 5 coils and the issue was the same...

    2017 Expedition - Jerky acceleration, misfires (P304, P300, P305)

    I fixed the vehicle this weekend so wanted to follow up for those interested. I decided to manually clean the carbon off the intake valves (I read that using a product like CRC cleaner through the intake is hard on the turbos). So I took the intake manifold off, cleaned all the valves...

    Thanks Jason. I just replaced the spark plugs and did not notice any oil seeping in the plug wells, however, can't say that I was watching for oil specifically. I didn't notice any on the plugs that were removed, and they actually were not too bad as they only had about 30k on them. I will...

    Thanks Joseph. We do a combined highway and city driving, so I agree MPG is a little low. That makes me feel better knowing that those communication codes may be due to clearing the codes, as they only showed up when I was actively using Forscan. Anyways, would you recommend that I use a...

    Thanks Joseph. Good to know that the injectors are probably not the issue here. Gas mileage has been fairly consistent around 13-14mpg. I already ran some fuel injector cleaner as a recommendation by the parts store where I bought the plugs (O'Reilly brand fuel injector cleaner). I didn't...

    2017 Expedition - Jerky acceleration, misfires (P304, P300, P305)

    Hello Expedition Owners. I have a 2017 Ford Expedition Limited (2nd gen Ecoboost 3.5L V6) with 120K miles on it (purchased at 72K miles). I am hoping for some help and direction with the current issues I am experiencing. When I punch the gas to accelerate rapidly, often times the truck will...
