Whats going on guys, I very recently started experiencing some pops and sputters in my idle and while driving at very low throttle (MAP psi @ -17 or lower). Also, if i bring the rpms to about 2k from idle, it just non stop sputters and pops. No changes in my setup just kinda started happening out of nowhere. No CELs but i have misfire detection off due to flywheel so idk if i would be getting one. But anyways, car seems to run completely fine at higher throttle and under more load, havent pushed it much though since this started. Car is heavily modified , will list below.
-Tuned by VitViper
-Ct Supercharger w/ 1000cc injectors
-Full bolt on i/h/e catless
-Clutch Flywheel (Misfire detection disabled)
My first guesses were ignition coils, or possibly injector related but im not knowledgeable enough to really know what the deal is, so any advice would be greatly appreciated.
On side note, i recently have been messing around with my secondary o2 sensor to try and pass emissions, and left the sensor unplugged. the sputtering (coincidentally i believe) started right after. the sensor is disabled in the tune so i dont think this would have any part in this but figured id mention it.
