This may be a bit long-winded, but this is where I'm at so far:
-2016 Ram 1500 Big Horn, 2wd, 5.7, 8 spd ZF, 113,700 miles
*I have zero info regarding the maintenance history, unfortunately*
When I bought the truck, it ticked when cold. The tick went away when it warmed up. I read through the forums and diagnosed an exhaust leak. Eventually, before I fixed it the tick stopped going away when the truck warmed up.
I included a pic of the driver's side where it was leaking, but the passenger side was also leaking with a snapped off stud.
after replacing both manifolds with new gaskets and hardware I started it on the jack stands and let it warm up. Noise was gone. I let it cool down a little, re-checked bolt torque, and then buttoned everything back up. When I drove it, as soon as I gave it some gas it made this awful noise:
youtube.com
Naturally, I assumed that I did a bad job of sealing the manifolds and that as soon as I put my foot down it made one of them start leaking, but I didn't feel like ripping it all back apart.
The next weekend I put it back on jacks and re-checked the bolt torque again. (I only have a 1.5 mile drive to work at 35mph)
Same thing as before: Everything sounded great, buttoned it back up, went to drive it and the noise is back. Now my assumption is that something in the fender liner, or dipstick tube, or SOMETHING external on the motor is vibrating. No codes being thrown at this point.
*sorry this is a ling story, but idk which details might be important here*
A few days later I am driving to go fishing and the check eng light and traction control lights both suddenly come on as I'm approaching a red light. Foot off the gas, but not applying brakes yet. The truck is in limp mode, but luckily I'm not far from my spot.
After fishing the CEL was still on, but no traction control light and the truck was no longer in limp mode.
after a couple of days of driving normally the CEL turned itself off.
(checked the code and got the P0344 camshaft position sensor intermittent)
That lasted for about a week during which the awful noise it was making stopped happening.
Yesterday, it went back into limp mode again with both lights. I shut it down and started it back up and still had a CEL but not in limp mode anymore.
During the drive home I got a #3 missfire code.
I watched a video on youtube during which a mechanic used a picoscope to trace a P0344 code to a bad coil.
I swapped the #3 and #1 coils, cleared codes, unplugged batt for a couple of hours. Drove a few laps around the block and codes were gone.
This morning the limp mode + dual lights happened again leaving my driveway.
I shut it down, and started it back up and it was no longer in limp mode. No missfires on the way to work this morning. I will be replacing all 16 plugs as soon as I get a chance, since I'm willing to bet they are the factory originals with 113K miles on them. I am curious to see if it missfires again if it will be #1 this time. And if a bad coil really can interfere with the cam position sensor signal.
IDK...... what do y'all think? Did I mess skmething up while doing the manifolds and cause all of this extra stuff?
I've only had this truck for about 2 months, it is my first Ram and I am about OVER it already
*ANY input would be greatly appreciated*

Vibration Noise?
