argh.... i had a #1 cel - o2 content in the exhaust. so i changed it with a bosch ($50). now i still have the CEL. someone just old me that bosch's read rich. i checked the price of the oem sensor, and it runs $150. i just need to pass smog, so i dont wanna blow $150 on my CX motor just for a stinkin o2 sensor. im thinking i should pickup a wideband (so i can use a a/f meter later) or an oem b16 sensor (which is the motor i plan to get)
