Having problems with my rzr I have a hard code for code 1127 and a 917 code knock sensor , I found the knock sensor loose so I retightned it but I still have the same code. On the 1127 overboost code I have a aftermarket bov and I blew out the boost controller and it’s not clogged don’t know what else it can be? I unplug the battery for a while and plug it back in and the codes come back right away
