2.4journey2013

Right where the secondary thermostat is, it looked like it came with a brand new seal on it that sits in that groove. That square looking one O-ring gasket I didn't know was replaceable.

Update: will be replacing both camshaft sensors either today or tomorrow and will reset the PCM to verify it has eliminated the check engine codes.

The housing itself doesn't look to be cracked. It's seeping from the cylinder head to where it mates at the secondary thermostat. can I apply a small amount of RTV to seal that? It's a new thermostat and everything drove fine for a few days then started excessively leaking.

By the way, thanks for everyone's input and suggestions on this.

Sounds good. Yeah the misfire code is gone and it threw a p000a and p000b. The car oil is not just dirty but was mixed viscosity, etc. I was reading that incorrect viscosity as well as dirty oil could effect the VVT Which would throw a code for Camshaft sensors in newer cars. I think I remember the slow camshaft response code sometime before and the owner got an oil change and I reset the PCM and those two P000a/b codes were gone until recently.

Looks like p0302 is gone but now I have p000a/b codes which is slow camshaft response. The oil looks very dirty so I'll be changing it fresh to see if that helps their response. If not looks like I'll be replacing the sensors. My question is, when purchasing the camshaft sensors are they the same 2 camshaft sensors for p000a and p000b just in different locations?

This seems to be almost the same thing as what mine is doing but is your stumble constant at idle? Or is it here and there comes and goes?

Might try that, yeah not getting any codes. Does this car have an in-line fuel filter near the gas tank? Possibly gunked up injectors, will be running some cleaner through it. I'm working on this for a family member or I'd have all the service manuals at least for my car, etc lol.

If for whatever reason you didn't complete this. Look at the intake manifold and then straight down in the middle towards the radiator on the 2.4. You will see the throttle body. Replace as needed.

replaced both thermostat even though it's 95*, the overheating seems to have settled down. I'm not exactly sure the low speed fuse is working for the radiator fan but when I was driving it didn't get above 200* and when I was idling it got to about 210-215* and it's still 90* weather outside. I noticed that the stumble happened. I went and added air to the tire and when I restarted the car it stumbled slightly for a minute or so but the check engine never came on. Once I pulled into the road it started to drive fine. The intake manifold gasket, if bad or failing would be constant. I dot think it would be ok here and then shortly leaking air. is there anything else I should check relating to the idle stumble? Air filter looks ok. I'm just starting to get stumped. could it be the Mass airflow sensor messing up?

yeah, looks like this will take a little longer than usual. I don't really feel like going out and replacing these parts in 100* weather right now! But as soon as it's completed I'll test drive and be back to this thread.

yes, it looks like there are 2 for the 2.4 2013 journey. One that sits in the plastic inlet like the above picture and one that actually sits against the cylinder head by the plastic water inlet.

I noticed the coolant wasn't flowing through the radiator just pretty much stand still the entire warm up (stuck closed?).I have purchased 2 Thermostats for the journey and will be replacing them shortly. I'll update this thread when that's completed. I have the new CPS installed but haven't driven the car since I put it in. Will test it out after the cooling parts are replaced and hopefully the misfire is gone.

Awesome, will do! I replaced the CPS but will wait to drive until I replace the t-stat.

Just a quick thought, could the EGR valve be causing an issue with idling misfire/stumble? I noticed last night I reset the computer, warmed it up (idled fine no misfire) took off And test drove about 5-6 miles with it as normal no misfire. I came to a stop sign shortly after and noticed the car slightly misfiring but no check engine light on, eased into the throttle and it drove as normal again for about 1.5 miles and I pulled over to check, still running normal. Finally got home and let it idle for a good while and it didn't Misfire. So it's very confusing. I noticed the coolant temp got up to about 210-212*F and that's when it seemed like misfire/rough idle at the stop sign but once it lowered back down it seemed fine.

Picking up a new CPS today or tomorrow and throwing it in, hopefully that does the trick.

When replacing the CPS on this car, does it have to "relearn" or is it a plug and play? Newer cars are such headaches.

Compression test completed: #1 210 #2 208 #3 210 #4 210

After I check those and come back with OK, I'll be at a loss. warming it up now for compression test with the computer reset. Seeing if it will misfire while just idling.

Checked the wires for that coil pack, everything seemed fine. I also checked the radiator for any exhaust fumes leaking into the cooling system via the tester and chemical color. Also was OK there. Will be doing a final Compression test this evening and if that checks out. -replaced Spark plugs all 4 correct ones -replaced coil pack for cylinder 2 (misfire) -getting fuel and spark before it randomly misfires -checked cylinder 2 coil pack wiring for cracks/breaks - none to me, I think it's an issue with the PCM. Why would it have spark 10 mins and then start misfiring with no spark on cylinder 2 for xx amount of time and then resume normal spark to all 4 coil packs and it's not the same every time it's intermittent. Doesn't the PCM control spark among other things?

Thanks for the response. it has 82k miles as of yesterday. all plugs were changed 3 days ago. Number 2 cylinder kept giving random misfire here and there. Replaced the coil For that one specifically. the misfire isn't there always, kind of like a ghost here and there but for whatever reason when it's happening I can unplug cylinder 2 coil pack and there's no change To the motor, meaning I'm not getting spark but why? And why at random times and other times it can drive for 30 minutes or more without issues. This is why I was directed more towards the PCM causing an issue with the spark for cylinder 2 randomly. I will definitely be doing a compression test today as well as checking for exhaust gas in the coolant as I'm getting slight overheating but could just be air bubbles in the cooling system. As for compression test in this exact car, do I need to pull any fuses before preforming the compression test? Or can I just unplug the injectors and remove the spark plugs and turn over the motor via push button? I'm used to older cars, mainly pre OBD2

Hey guys, 2013 AT Dodge Journey with 2.4L. It's getting a random misfire (losing spark) at random times and it seems to be the same cylinder each time it does it. It's not consistent but more of a here and there. -I've checked the injectors, good -coil packs good, even bought a new one for cylinder 2 (#P0302) will be doing a compression test tomorrow. this seems like maybe a PCM issue? Can anyone else throw out any ideas? Thanks!!
