Itís compression. One or more of your cylinders have worn or cracked rings, possibly a valve issue (lash way out or valve not seating). When the engine gets warm enough and metal expands, compression increases and you can squeeze the air in the cylinder enough to generate enough temperature to immediately burn all the fuel injected into cylinder.
You probably didnít want to hear that. I have well over $100,000.00 into my 2015 and only 40,000 miles, I have the same issue but my problem may be from bent connecting rods from too much power.
I just bought a whole set of factory new Bosch injectors and installed myself. Didnít change a thing, I am literally refinancing my house to pay off $50,000.00 of credit card debt mostly from truck and have some cash to replace rods/pistons, hone cylinders or bore over, maybe just get a fully built performance engine if it looks bad.
Iím 6í4Ē and my truck is my Sports Car/Hotrod, since I canít fit in one, but I had no idea what it was going to cost me and I donít even have my compounds yet.
Post your truck details and mods if you want a more detailed answer.
Good luck, Tom J.
