So I'm being honest I recently changed the timing belt because it snapped when I was driving and it caused a crank no start I'm going ahead and list everything that I replaced.

Fuel pump
Fuel sending unit
Serpentine belt
All spark plugs
All Mini fusses
Camshaft position sensor
Water pump
Battery
Crank pully
and last the timing belt

So, after my timing belt replacement the car started but its running rough and the engine is really loud and sometimes it will start right up and idle rough and sometimes it will start than stall out on me so recently I started it up and it was idling rough my rpm would jump back and forth from 600 to 65, 700, 800, 900, and 1000 just back and forth and when I put it in drive or in gear it would idle more rough and shake but when I put it in drive and started pressing on the gas it would run smooth as long as I'm pressing the gas I went around my block while just mainly pressing the gas and a little break but once I take my foot of that gas it will just completely shut off on me and when I try to start it back up it start but immediately dies unless I keep pressing the gas I have to wait a long time before my car can start without pressing the gas I scanned for codes and I got a p2314 code basically saying I had a problem with my ignition coil “E” so I checked my cylinder 5 coil and just swapped it with another coil from cylinder 3 didn't change nothing and still got the code for cylinder 5 I have no idea what to do now it was running perfectly before the timing belt snapped and once I replaced it that's when it started acting up I made sure the timing marks where all lined up over and over again even got a mechanic to do it once and it's still the same I don't even know how many times I had to keep going back and forth with my engine taking it apart and fixing timing and putting it together.

So, if you have low compression in #5 cylinder it will cause this code: The P2314 code for a 2005 Chrysler 300 indicates an issue with the Ignition Coil "E" Secondary Circuit. It does not happen very often with timing belt engines, but you could have bent an intake or exhaust valve. If you remove the spark plug and use this guide, you can confirm the issue:

Then the cylinder head will probably need to come off unless you want to do a leak down test which injects air pressure inside the cylinder to see where the air is going, intake, exhaust or crankcase, the crankcase is less likely, but you never know.

Here is how to do the leak down test:

Let me know what you find please.

Is my engine an interference engine? Did I bend valves because when I was driving my car completely lost power and stalled out on me and my timing belt turned out to be snapped?

This is with my car running these other codes popped up. I started my car and it took a little while before it started when it did it idle at 1,100 for a but then dropped down to around 600 700 and keeps going down and up.

Yep, low compression can cause all of these symptoms, even though your engine is a non-interference it still could have touched the valve, so a compression test is where we need to begin. There is a chance the timing belt was not installed correctly but let's do this one step at a time. Thanks for the video. If you can upload one from under the hood of the engine idling, I can tell if the engine is hurt or not.

Thanks for the video. Yep, it sounds hurt to me. I would do the compression test to confirm. Let me know the readings please.
