My Check engine light won't go off on my Miata 1999. I see everyone having trouble, but mine is the code for the Heated O2 Sensor, which I REPLACED (not cheap). Now its on and off, and i have the SAME obdii code for the O2 sensor, what do i do??? I LOVE my miata (new to me) but when that engine check light is on, my car runs like crap, when its off, it's great. NO other codes are showing up. help! email me if u can @
