2018 2.7 has been struggling to accelerate uphill these past 2 weeks. No engine light, and my scanner shows no codes. I don’t want to replace all 6 coil packs without some kind of clue. It’s getting worse (now it’s just struggling to get home over the hills), and I found a mode in Forscan that gave me a clue!
I found no pending codes, but “Mode 6” in the main menu selection counts misfires. Ordered two coil packs. Forscan for the win (packs 5 and 2 … pack 5 showing many misfires, 2 showing a few, and the others showing zero).
Also lost heat for a day this week - the H/C blend door servo stopped. That code did show in Forscan, “connection lost with…”. This will be the second hvac servo to fail. That may be a full dash-removal job when it finally goes. Trucked just turned 77,777.7 miles yesterday. I have this pit in my stomach that it’s time, earlier than planned. I’d been looking to just get a smaller DD, but all this plus the discovery of the finest metal glittering in the last oil filter has me at least thinking about it. I’ve had a love/hate relationship with this truck. It drives wonderfully, handles perfectly for my use, gets good gas mileage, and has a quiet interior, and not too much tech (my preference). Not sure I could do another ford. Don’t want Chevy styling. Ram has its appeal, especially the baby diesel, but I don’t trust Stellantis and the local dealer is awful (I owned two jeeps and was there regularly for warranty on one of them).
One coil pack arrives today. Maybe I can get it in time for a quick repair. Fingers crossed for #5!
