DID NOT STAY THAT WAY lol. The vehicle ran fine when I took it for a 15 minute test drive but the next morning, my wife started it up and drove it out of the driveway. It shuttered and threw another code. I read the code and it showed cylinder 1 misfire. So I ordered an ignition coil from my auto parts store and shipped it to my house. My wife installed it today and it works great so far. This is the second ignition coil made by Duralast that has been bad and I have had to replace. I bought the "Four pack" of ignition coils last year and within a month I had to swap out of the coils. Now I switched out my second one. In the end I think the issue was the ignition coil on cylinder 1, that misfired and threw the CPS off. From now on, I think I will order Mopar parts only for my Dodge when it comes to the engine. Thank you all for the help and advice!

UPDATE on FIX: Ok so I bought a Mopar CPS for $28. Installed it and it still did the same thing. I bought some CRC Intake and Turbo cleaner ($14) from my local parts store and performed the "Professional" cleaning listed on the bottle. The vehicle runs like a champ now and no codes!

UPDATE: The vehicle has 140K miles on it. I used AC Delco ignition coils from Auto Zone and had to replace one under warranty already after I installed them last year. But the update is, last night after driving around, a CEL came on. I got home and checked with a scanner and it showed Cylinder 1 misfire. P0016 and P0301 and it runs rough with a shutter more often. I am going to get some CRC intake cleaner to try and blow out the carbon from the pistons tomorrow and see if that fixes the misfire. I still don't see how this could have happened overnight after changing the CPS. It was not an OEM CPS as asked above. Funny thing is, the first one they installed had to be replaced because it threw the same code the next day. It was chalked up to "dead on arrival" part and warrantied.

My 2015 SE (2.4L) threw a CEL that said it needed a Crankshaft Position Sensor. I changed it out and CEL reset. All runs fine but now I have a little engine sputter every couple of seconds. This sputter can be heard in the engine bay and also heard in the exhaust as if it might be a misfire. I have already changed the plugs and ignition coils so I know it can't be that. This only happened after the CPS was installed. I have read through the forum and some say it could be carbon build up but I don't see why it is all of a sudden after CPS change. My acceleration is smooth and it does not noticeably shutter while at cruising speed. Very few times, it has shuttered at cruising speed but not as often as at idle. I have put Seafoam in the tank and ran through a gas tank but no change. I have used 93 octane but no change. The mechanic showed on the computer that the crankshaft desired setting is the same as actual so there is no change there. Any suggestions?
