I had to buckle up also.

Did you do a hard reset to your pcm and tcm? I would try that, especially since you changed those sensors. I'm sure the fuses have different numbers just pull every fuse that is labeled pcm and tcm even the big square one. I had four fuses that were connected to my pcm and tcm.

Also, I'm about to get rid of the resonator and change my catalytic converter from an C.A.R.B. emissions to federal emissions one. And of course, grab a muffler while I'm at it. I'll update progress.

I have an intake. You gotta build it yourself. No maf sensor adapter fits cause it's not a maf. Lol. I actually cut the collar off the stock air box!! A dremel tool works great. Some sanding and wa la. It has the original fitting for the IAT sensor AND get this....a bell housing for perfect air redirection from the sides. Another reason is that it deletes the free air hose, which you don't really want. You could get residual oil sucking back into your throttle body. Just put a crankcase filter on your crank and it actually adds about 10% to 20% of power. But the thing is, that with such a newer car, you'll have to hard reset the pcm and tcm back to factory settings and go through a couple of true drive cycles to make your car recognize the change. Make sure when your doing your drive cycle that you don't have your lights on, a/c running or radio on. I did it to my '19 2.4l journey blacktop and it runs amazing. It took me about a month after I bought it to realize it was sluggish and gas mileage blew. I'm talking 285 miles per tank. I've had it for 3 months now. So I changed my exhaust vvt solenoid, my crankshaft position sensor, and ambient air temp sensor. Now it get 365-420 mpg, my throttle response is greatly improved, and I don't unessesarily stay in gears so long when I'm not on it. I've got a carbon fiber heat shield on its way as we speak. I'm working on building my air cleaner tube cause you may have to. Idk if yours has intake systems for it cause they have no intake systems for my car. Don't know about the tuner things. I've seen them, but I don't think they do anything.

Reset pcm and tcm. Just make sure you pull every fuse that's labeled pcm or tcm.

That way won't work. I'll post how to do it properly. Fuse numbers are probably different, just make sure you pull every fuse that is labeled pcm or tcm.

The fuses numbers may be different, but make sure you pull everyone of them that has pcm or tcm on it. I have four in my '19 journey.

That's a myth, it's not the correct way to reset pcm.

Most scan tools won't reset pcm. Do this: I'm my 2019 there are 4 fuses that control the pcm and tcm. Yours might be different, all you do is look at your fuse box top and any fuse that has pcm or tcm on it, pull them out. Even the big square one. Then get in the car, close the door, and put on your seat belt. If it's key operated turn the key to the acc option, wait for the binging to stop. Then hold down the brake and turn and hold your key to the start position for about 5 to 7 secs. You'll heat a chime, keep holding it for another 5 to 7 sec until you hear a second chime. Turn the car off and put the fuses back. Start the car and take it for a proper drive cycle, no a/c or radio or lights.

Not the way to do it. Try resetting pcm and tcm. If you want the procedure let me know, it's not unhooking the battery for 5 min.

Did you reset your tcm and pcm?

Did you try to reset your pcm and tcm?

Update: Just learned that if dtc pops up and you clear it the system will not test that dyc again until you fix the issue, unless it's way out of the normal numbers. So I checked my freeze frame and there was a previous code stored in the system. Had a bad exhaust side variable valve solenoid. Replaced that. I changed my IAT sensor collar. I literally cut the original collar off of the original intake box it was connected to cause it had a bell housing around the inlet side. Did some sanding and shaping and it fits perfect. Then I read that I need to reset pcm and tcm. Alot of people said disconnect both battery terminals for at least 5 min and touch them together to clear out stored power. That was wrong. I actually had to pull 4 fuses, then get in the car amd buckle up, press my start button to acc and wait til the dings stop, then with my foot on the brake push and hold down the start button for like 7 to 10 sec until your dash chimes. Some dodge models you have to continue to hold for a second chime. Mine didn't do the second one. After the chime, turn the car off, replace the fuses and take your car out for a proper drive cycle and wa la, I'm now getting 375 miles per tank, my throttle is responding much better. And you can actually hear a difference in the air intake. All my numbers look perfect and everything read ok on my i/m readiness.

So I changed the pcv valve, and installed the crank filter. Don't know how much it's accomplished gas mileage yet, I'll give it a day to get a good read. Sluggishness wise, it still slugs. Lol. I haven't replaced the short ram pipe yet. But when I do I'm gonna redirect downward more and install a heat shield completely around the filter except at the bottom so the air will be coming from under the car. I'm reading pretty high temp on my intake air temp. It got up to 100° today. And I was reading mid to upper 90's iat. Even on the interstate. Hopefully I'll get better temps after I change it up. But what I have further found out is that it's a CARB emissions vehicle, not a federal. I'm 40, and everything I've ever heard about California emission regulations on vehicles make them run like shit. I've done a little research and it's half and half. Half say this, half say that. I'm sure emission stuff like sequential fuel Injection and a heated o2 sensor aren't the problem, but could the three way catalytic converter and exhaust be the issue. And are there other emission stuff that could effect performance. Ive lived in memphis my whole life and have never had a CARB emission vehicle before.

Yes, it runs. Awful gas mileage (12 mpg) and sluggish though. It has some hesitation on the interstate, especially going up hills. I'm changing my intake tube to an aluminum one and adding a crank filter instead of the free air line. I'm gonna check my pcv and other senors also. I'll find the issue.
