Excuse me for the long write up. I bought this 2012 Raptor about 6 months ago. It had 70k miles when I bought it, and now it has about 74k miles. Great truck. But I am running into some issues.
Note: Since I first bought it, it always had the slightest of hint of shaking at low speeds/low RPM. I figured it needed a tuneup and didn't think of it much as my 2017 F150 3.6 v6, which I bought brand new actually does the same thing...
So in the past three weeks I've been running into an issue that maybe slowly getting worse:
Three weeks ago while refilling at the gas station, as I finished filling it up and turned on the truck, the truck started to hesitate pretty badly and was sputtering. So I gassed it pretty hard, drove it it around the block and the truck was able to situate itself and go back to normal. I had this issue before with other vehicles and figured it was probably due to a failing purge valve. Since then I've been using 93 Gasoline and have not had this issue.
Two weeks ago while going up my driveway which has a steep incline I stopped at the top as I forgot something I needed from the house, so I put it in reverse to go back down and the truck lost power, oil pressure light came on and the engine shut off. I checked the oil and it was full and clean and checked for leakage but couldn't find anything. Went back into the truck and it turned on with no problems and I could not replicate the problem. Doing some research I found that this particular scenario has happened to a few others with their Raptors (going up a steep hill and losing power/low oil pressure warning)
One week ago I was driving to the supermarket. As I got to the red light stop, the engine started to sputter and hesitate pretty rough. The traffic light turned green and as soon as I pulled into the parking lot and into the stall the truck shut off and low oil pressure came on. Shopped, came back to the truck, turned it on and it turned on with no problems and drove home fine.
Current week the truck has been behaving well with no shut offs. Although I do feel that the hesitations/shaking are much more frequent while cruising during low-mid speeds. I've been taking it over some steep hills while going very slow and it's been doing just fine see if I can get it to act up again but it's doing just fine. So I'm confused.
I will be replacing the spark plugs and all the coils as well as the purge valve. I feel like a misfire is eventually causing the low oil pressure engine shut off to go into effect. I read online that on the 6.2 v8 it takes very little for that mechanism to trigger a shut off and that's how they're designed.
Has anyone had some sort of similar problems to mine? I'm getting no check engine lights other than the Oxygen sensors that has been on since I bought it. Nothing for cylinder misfires but from past experiences, the engine is behaving as if something is misfiring.
Thank you for reading and appreciate any help or insight.
