I have a 2017 Chrysler Pacifica and it started having a misfire and when hooking up my code reader it was showing a few codes. P0019, P000C, P0300 were the codes thrown. Not being a mechanic I decided to change the spark plugs and this didn’t help at all. I then changed the camshaft position sensor and it didn’t help at all. I took out the Variable timing solinoid and cleaned it up, but still no change in how it run. After reading and doing research I seem that the crankshaft sensor(which was terrible to find) could be the issue so I replaced that and it seemed to be better than it was, but after the van warmed up it would start misfire again. I took the bank 1 and bank 2 vvt exhaust solenoids off and cleaned them and swapped them to see if my issue resolved from cleaning them or switched to bank 1 which would tell me the vvt that was in bank 2 was the issue. Unfortunately I think there is an issue with the timing chain in bank 2 side of the engine, but didn’t know if someone else has experienced this issue and found something else that caused it.
