Been following this thread is it possible #1,7 have a problem and start acting up when you accelerate it, the last video to me doesn't sound like anything is wiped out yet, how about raising the idle on that hot start engine and record it, and see if the noise increases, and it might be time to pull the valve covers.

Just looked at the first page, seems to me you are tossing in the towel when you don't even know what the problem is, look at the plugs, do a compression check and see what that shows. try a different coil. could be simple.

I just had the same problem, May 1st. The engine stumbled around on acceleration. 2011, 1500 with 85,000+ miles. It happened on the way home from vacation about 400 miles from home. Went to Peterson’s Automotive (RAM) dealer in Lumberton NC. Misfire #5 Cylinder. They did a tune up and took it for a test run. Computer still showed misfire #5. There was no ‘tick’ since the cam roller froze and was still against the cam; not as if the lifter collapsed. The bill came out to around $5,700. I saw the cam and it was a goner. Luckily, I had purchased a warranty through Zurich American when I bought the truck in 2015. The dealer had permission to repair in 10 minutes over the phone. When I picked up the truck four days later, Zurich had already paid the bill, except for the tune up items of $600. Another 1500 with the same problem was there and they were waiting three weeks for approval to repair. I heard the service manager calling the used car manager telling him to look into switching to Zurich

I've been changing the plugs in the truck on a yearly basis since 2015,so i have it down a bit,but i will admit swapping the plugs in the wifes car is alot easier,lol
I've have a 2005 with 44k miles. I changed the plugs ONE time and I was so stove up (southern talk) neck and back, with cuts and scrapes on my arms. That was 8-10 years ago. Now that I am really old and wore out, I'm not sure if I would pay someone to do it (I don't trust ANYBODY with my vehicles) or would just take a week or two to do it and then another month to recoup. I can't even image doing this every year.

I've run redline since 40k when I bought it and I always turn the MDS off.

I was driving last night on the highway and the truck started to shudder, and the engine light came on. I pulled over. I happened to have a code reader in the truck, and the code came up as Cylinder 7 misfire. I cleared the code just so I could get home and it started and ran fine other than it wanting to shudder a little bit with light throttle going up a long hill. Regardless, I think we know what's going on. The more I drive it, the more damage I'll do to the cam. So I'm just going to leave it parked for now.

I'd love to just take it somewhere, trade it in, and pick up another vehicle so I don't have to deal with it. However, trading something in with an engine light on seems like a great way to get nothing for the trade in. Right now there is no code since I cleared it, but I'm sure if I drove it around enough it would come back. If I tried to trade it in without a code, I'm pretty sure the dealer can tell that a code has been cleared recently.

I was going to start calling around today to shops and see if they would quote me cam/lifters. I'm sure they'll want to diagnose it first and try coils/plugs etc, but it's likely we'll end up at the cam/lifters. I'm probably looking at a $5-8k repair here on an 11 year old truck. It may make sense to fix it since a comparable truck is probably still ~$25k here right now.

any thoughts on how to approach this?
Thoughts...yep...Stop using redline and turning off the MDS. you are not helping anything. No one has any proof thatg using redline will help anything, and turning off MDS is an old wives tale sort of thing. Ya ought to run the damn motro like it was designed to run and you'd be better off. Cam failure could be, there have been some, just like GM and Ford have had some with their V8's, and even more with their V6's. Sori to hear of your problem but don't paln it off on someone else by trading it in, bite the bullet and fix what needs fixen, you'll be better for it, not richer but better. cheers

i've got the battery unplugged. We'll see what it sounds like in a little bit. It was squeaking like crazy earlier when I was driving it though.

its strange though - everytime I pull the plugs and put a different coil on it runs fantastic, but then gets rough and worse and worse.
I wonder if the unplugging battery is making it run better and not anything you are swapping or changing.

I wasn't disconnecting the battery until I had the plugs out the 3rd time.

I've since disconnected the battery and swapped coils again and it's no longer improving. It's just getting worse. The only way to be sure now is to pull the valve covers, and I'll have someone else do that. I've talked to some local shops that seem competent and familiar with the hemi.
