I have a 2005 Wrangler SE with the 4.0
I have 2 PCM one OEM and one @Wranglerfix... The OEM has 4 O2 sensor codes that won't go away and this is a problem with the PCM... but I don't have P0157.... when I plug in the wranglerfix pcm I only get code P0157. I don't know why i'm getting the code I have 4 new O2 sensors installed the proper NGK ones. I also have 2 new precats so I know that's not the problem. All of these parts have less than 2k miles. Does anyone have any thoughts? I've looked at the wiring and the wiring seems fine, i've had 1 mechanic look over the wiring and he said it was fine.
Anyone else have any thoughts? I couldn't find too much online other than what i've already listed here.
