02 Sensors: are there compatibility issues with aftermarket ones? I had 1 bad one and 1 that I feel is not 100% compatible.
I bought 1 aftermarket off Amazon and man was it horrible; car would buck and headbutt every time leaving from a stop. Ordered another brand/seller and it worked but I still feel like it's not working 100% like I remember it. I unplugged the 02 sensor and drove it and it felt more like I remember it. What do you guys recommend? Car is a JDM 2003 WRX STI with a 6spd
