what codes are getting? could have damaged the o2 sensor(s) and thats why you're throwing a code

Did you clear the codes after putting the OEM ones back in?

I'd check and make sure you have the O2 sensors in the right banks.

I did let it run in for bit and my check engine never went away so what I did I clear it with jb4 and than when I turn the car check engine pops back on...so later on I turned the jb4 off completely without deleting the check engine drove it for about 23miles still on...
