I had no codes prior to start of this, injectors cause erratic fuel mixture causing my PCM to fry it self and fried my new throttle body so new PCM and new new throttle body and I'm golden now haven't had any issues since Monday when I had those done

This guy works on a lot of journeys there was 4 others parked out front when I went to do the TB relearn and ya woulda been ALLLOOOT. more expensive cause he didn't charge me for the relearn or the further diag. Dealership wanted $200 just to diag prior to even doing a relearn which would have been another 190$ and then they'd wanna keep it to do the PCM which would be 1200$ and instead it's gonna cost me $350

UPDATE: Ended up throwing in a new Throttle body as couldn't perform relearn on the old one to see if that solved my issue. Took for a drive ran great till my oil and coolant temps hit 96c & 106c then would throw P2112 & P2118 along with limp mode. To get it moving again I'd have to reset the PCM and disconnect and reconnect The new TB. So brought it to another local shop. He walked me thru the relearn then I got the journey back to those temps and sure as shit same codes popped back up. So we dived into to it together for bout 10 mins and got all other codes to clear except the P2112 ( etc unable to open - bank 1 ). Main causes for this code are electrical issues ( that was tested and in perfect condition ) and PCM malfunction/Failure so Monday get to take yet another day off and get a new PCM thrown in 👌

I have a 3.6 V6

So we are back to OEM and the rich running persisted. Code is p0172 ( bank 1 ) starting to wonder it is MAP sensor or Bank 1 02 sensor 😕 everything runs stable till it starts to warm up then the fluctuating RPMs start to happen about 5-6 mins after starting.

Turn out it was the coil packs I ended up pulling them and noticed the amount of movement the spring contacts had with no permanent mounting to the head so I put my oems back on and went a got some NGK plugs to throw in, just throwing in the scanner and clearing some of the shit and firing it up hopefully last problem !

Figure almost 10 years ( 3900 hours) of running a fresh set wouldn't hurt

hey guys, im currently at a huge loss and baffled by the current standing of my 2015 journey crossroad. i recently bought this unit in Sept/23 with 152000km . So far Ive had my transfer case split in half from the inside, leaking OCV seals and VVT seals all replaced at dealer and fluid changes. i decided it was probably time for Plugs, coil packs and injectors as well. these i didnt buy from dealer ( never had an issue before). changed all these parts plus gaskets, ended having to do almost every vacuum line and now im stuck with a P0172 code ( Bank 1 ) ( running rich ). i reverted back to my old injectors cause thinking the new ones may have been throwing too much fuel into the system. got everything back assembled and torqued down and the problem still persisted. decided to check my oil and it smells like 50:1 mixed fuel for lawnmower. gonna change that tomorrow. but do we have any ideas or thoughts on how i can cure this running rich issue ? cause im seriously baffled by this one. i do have access to code reader with Mode 6 and live data as well.
