hey guys. i have a 2013 si tuned for a catless exhaust and cai. i live in NYS and have to get my car inspected. last year all i did to get it to that point is swap my tune back to stock, drive it to clear the monitors, get it inspected and put the tune back on. however this year, with no other engine modifications done to the motor since then, i have a rough idle that goes up to abojt 2k then drops back down and it continues to do that this throwing a P0507. i never had this issue before, but does anyone have any ideas as to why that is and how i can get it to stop? i already cleaned my filter and maf sensors and reset the ecu. would it be the map sensor? car has just under 118k on the clock. any information is appreciated thanks in advance guys

oh my bad lol i didn’t see that in the first reply. i don’t have access to one of those. i remember seeing somewhere you hold your rpm at a certain number for a specific amount of time, but i’m not sure how true that is
