My 2013 2.4 no too long ago have a misfire and goes to limp mode, but the code was P0303 (I used WiTech scanner), after I change the injector #3 the problem was fixed.

Did you use OEM sensors? Most of the sensors in the Journey are hall effect and no OEM could give you headaches.

Try cleaning the ABS connector with an electrical cleaner spray can, always remove the negative cable from the battery, remove the ABS connector module and spray the male and female connector with good amount of cleaner. I use the WD40 contact cleaner brand.

The head gasket is below the valve cover (the one in the picture) has holes for the oil and water circulation and have the intake and exhaust valves

Is a 2.4 engine? if Yes, it sound like bad idler pulley or alternator decoupling pulley. Remove the serpentine belt and start the engine, if noise is gone then you know is any of the 2 choices.

If it goes to 2000 RPM for 2 or 3 seconds is probably OK, if it last more than 30 seconds I will recommend you to change the intake manifold gasket as those engines with the plastic intake tend to leak.

You can try going to  a junk yard and look on any open engine for a bolt similar to  the one you need.

Replace both thermostat and drain the coolant (use the screw at the bottom of the radiator to drain it) and replace it with new coolant, you can use the one that is compatible with all coolants.

Read the attached pdfs, it may help you.

Remove the hose from the air filter to Throttle body at the air filter, start the engine and block the opening of the hose with your hands,  engine should shut off if you do not have a intake manifold leak, if test pass, I would check the compression of every cylinder, Harbor Freight has a inexpensive kit to do it.
I have some nightmare issue that I fixed more that a year ago, it was a small intake manifold leak, but you are no having same codes as mine, see it below
P2173

Is no hard to change it, maybe 2 hours, search for a video, is same as the Avenger or other Chrysler with same 2.4 engine, the code has no return after the fix.

My 2.4 liter 2013 with 80K got the P2173 HIGH AIRFLOW/VACUUM LEAK DETECTED (SLOW ACCUMULATION)
I ran a smoke test and no leaks from the intake or any hose, I replaced the Throttle body and the code return, I replaced the Mass sensor and the code return, I replaced the Brake booster and calibrated the Throttle body and the code return after 3 weeks, finally I decide to change the intake manifold gasket 2 months ago, so far it looks that is fixed for good, I found the old gasket was leaking between two cylinders thus the reason the smoke test did not work, to any one with this code I suggest to replace the gasket first, is only $6.00. The P2173 will put he car in limp mode and make it undriveable

I have a 4.3 and upgraded last year with this one, S100 C268:

So far is ok but no perfect, I installed a wireless backup camera so I did not have to run any wire, here is the link to the camera:
