but it looks like its the o2 sensor because in OBD section it said fuel air metering ther was like 7 differnt things about that. so ill get that changed. are there Two O2 sensors in the contour is just 1. i say there is 2 but my friend keeps saying there is only 1 o2 sensor.
the obd test also said Auxiliary Emission Controls i have no idea what that is.
i dunno if i have trottle hang fix or not, how do i know if i have it or not.
You will have two or four, depending on Zetec (2) or Duratec (4)
However, only the sensor(s) upstream of the (pre-)cat deal with fuel mixture. The downstream sensor(s) deal with cat efficiency.
Make sure your car is warmed up. You could blow high HC if the engine is cold.
But it sounds like you have a code or pending code if you failed the OBD check.
