Hi guys, my 05 tj started idling rough and throwing a p0113 and p0123 code changed both sensors and the map sensor since the ait goes through the map to the ecm still having some issues wiring harness seems fine i didnt remove the whole thing to inspect any insight to finding my issue ?

What brand sensor did you use?
Do you have the original PCM?
Might want to talk with Mark @Wranglerfix www.wtanglerfix.com about your PCM.

Bought crown sensor. Only had the jeep for a year pretty sure its original pcm
Auto? Manual? Four cylinder? Six cylinder? Tell us a bit more about your Jeep. Fill out your profile while your at it for better educated guess from us. Miles?
I have not. With the codes point to sensors i didnt think to look there oil pressure is good. I did notice my dash light flickering maybe a bad alternator pishing highvoltage didnt think it would make it idle rough tho
Low battery will make these rolling computers act wonky. But you can load test it to see if there’s an issue there. Surprised @macleanflood hasnt suggested grounds yet. There are numerous grounds that if not clean and secure might make your gauge lights flicker as you speak of.
your symptoms are leading back to the pcm. Get the Jeep up to operating temperature and gently tap on the PCM with a screwdriver handle and see what happens.
I went to check all the grounds on the engine block when i grabbed all the sensor grounds and wiggled them 3 stayed in my hand and the rest broke out with slight pull my alternator had stopped charging. All wiring redone managed to get it running again now throwing p0031 37 51 and 57 guessing killing my battery did that
