So i installed an 02-04 primary o2 on my 05 so i can run k-pro. everything was cherry for a day until i tried running some datalogs and i was getting a primary o2 code. i cleared it a couple times thinking it might just be the car not liking the different o2 but then i started hearing a rattling sound coming from the area aroung my header and am now getting a "heated primary o2 code." i checked under the car and all the connectors are secure and both o2 sensors are definetely in all the way. Once i got the heated primary o2 code i stopped picking up a/f on my data display on my laptop. Did i fry my primary or what?
