100% a valve open (broken spring). I did a cam job for a guy locally who supplied his own push rods. After getting everything together and trying to start it, we got those same TB codes. Reason was a push rod was too long and keeping a valve open. So when the piston was coming up, it was pumping air back up the intake and pushing against the TB butterfly, thus the TB codes

Well finally got back out there to work on it. Pulled the intake, definietly split. I did not physically see a broken spring, but will change them all. I am sure that is the problem. I do need to order one of those fancy spring compressors though? If you could help me out with that, I would appreciate it? I also need the number for the guy who in Texas that sells the 6.1 springs and rods?
Thanks for all the help

Just got the parts from Henson Motorsports. Shawn was a great guy to deal with. I got the springs and pushrods for $98.60 shipped to my door in 2 days. he also got me a brand new intake with the upgrades for 240 shipped to my door. I ordered a spring removal tool from Manley valves. It looks like a simple little gadget. It does not use bolts, just putting pressure. (I'll probably need a third hand for that).

Same problem
Just finished looking over the PCM connectors. They looked ok. Gave them a full once over and lightly packed the connector sides with silicone grease.
Hooked the battery back up and started it.
It immediately rev'd and then started it's horrendous idle.
Current codes are:
2108, 2172 and 2106 twice.
2003 Ram 1500 5.7
60k miles
Haven't had any problems until now.
History of problem:
Drove home to/from work as usual. All was fine until I was about 1/8 mile from home. Right when I turned on my street, the Hemi started to run like Chitty Chitty Bang Bang.
It was everything to get it backed into my garage. Misfiring, stalling and wouldn't stay running unless I kept my foot on the pedal.
So there it was....a heap, but thankfully in my garage.
I pulled codes and got P0108, which is high voltage-map sensor.
Off to the dealer I went to get a new map sensor.
Replaced map sensor and problem remained.
I cleared the code and it didn't come back.
I figured I had something in the fuel, so got fuel system cleaner and tried my best to keep her running to get it through the injectors. No mosquitos for miles while I did this. The truck ran major rich and was stinking out the neighborhood.
I figured I'd do the basics...
So I changed spark plugs and wires and cleaned the throttle body.
Put everything back together and started her up. Still ran like crap, but would stay running without foot on gas pedal.
Shut her down and disconnected the neg. battery to reset computer.
Hooked everything back up and started her up.
Same as before, but had a nasty backfire.
That didn't sound good.....and now pushing on the gas does nothing.
Shut her down and checked everything out. No clue.
Checked codes and had P2172 and P2108.
Replaced throttle body with new one from Stealership.
Reset PCM again with disco of neg. battery terminal.
Start her up.
Same ****e.....and pushing on the gas still has zero input. Like not having a gas pedal.
So:
Replaced plugs, wires, map sensor, throttle body and checked and rechecked all wires/hoses.
Stumped.
