Aem ems to stock. O2 sensor issue
Just put back my stock ecu and within 10 seconds, saw a check engine light. Ran the codes and it seems they are all related to the primary o2 sensor. I remember when I had my Aem ems with a/f, my tuner used the wideband sensor as the primary added something/spliced the wiring to make it work. Now that this is gone, could this be causing this issue or can it be the o2 sensor.
Has anyone had this issue before? The o2 sensors were just tie wrapped outside the car for about 2-3 years.
Thanks.

You probably need to buy a new sensor. Pretty sure moisture isn't good for the sensors and I'd assume they saw a lot of it hanging out on zip ties under your car. Also sounds kinda sketchy about the wiring, lol.

Got a replacement used from a 04-05, received new engine codes. So I just ordered a denso replacement on eBay for 90 dollars. Should come in by Friday. Can let you know then if it fixed it.
