do you have aftermarket headers.. with hight flow cat.. that will cause to throw fualty o2 sensor.. but my guess higher cc injectors could but i havn't heard it should.. make sense.? i would answer no.. but a high flow cat should..
I've been searching every damn forum on the internet as well as google, and I can't seem to find a basic answer. Will having a K24 with 310cc injectors on a base K20 ecu cause me to throw a faulty primary o2 sensor code? I'm just curious as to whether to replace it, or just let it be for now.
Thanks

High flow cat shouldn't effect the PRIMARY O2 sensor at all. It would effect the SECONDARY, but that is not the OPs problem.
I don't know for sure, but I don't think the engine/injector/ecu combination is the problem. That combination should run very close to stock a/f ratios and that is all the O2 sensor cares about.
