hey everybody, I have a 93 F150 with a Jasper 302, long headers, and true dual exhaust, all on the truck when i got it. It has always ran a little rough particularly at idle. I decided to dump the codes and I am getting a "52" KOEO code and "33" (EGR valve) and "41" continuous codes. The continuous code "41" is "HO2S - no sensor switching detected." So the million dollar question is will the O2 sensor ever work properly with dual exhaust. Since it only measures half the exhaust with this set up i am wondering if that is the reason i am getting this code. Thanks for taking a look, any feedback is appreciated.
