Codes P0300 and P0014, car jerking in idle with eco mode on?

So it looks like the is still having the issue and acts like this when the camshaft timing is off or can't be controlled, how long have you driving the car once the last repair was done? Here are what the old codes mean:

P0300 - Random/Multiple Cylinder Misfire Detected:

P0014 - "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1):

It could be you have no codes because the car needs to be driven longer for it to trigger, I would scan the car now to see if any are present.

I would also make sure the engine oil is clean and full with a new oil filter because it is the oil that operated the camshaft actuators. Please go over this guide and get back to us.

I start driving the car right away after the repair and it was fine and then I put some oil in my car because the dip stick is hard to read and I was told the 2.4 runs through oil fast and to make sure I never get low and right after I put the oil in and drove home it started to do those symptoms and then the next day it stopped. I’ve drivin atleast 200 miles since then no symptoms no CEL. I have A oil changed scheduled for tomorrow.

Yep, clean oil at the correct elel can help it, also ask how dirty the oil was as well. Lets hope for the best.

Okay, got the oil changed new filter didn’t ask how dirty it was didn’t see your response by then. Hasn’t done any symptoms and no CEL.

Fingers crossed :) let me know if you have anymore issues. Have a great day!
