got the codes for my CEL pulled yesterday, and i'm unclear on what exactly they mean - and what needs to be done to 'fix' them.
Code P0140: O2 Sensor, CKT No Activity, (Bank 1, Sensor 2)
Code P0037: HO2S Bank 1 Sen 2, Heater Circuit, Low
i have a header with the non-fouler; it's been on the car and running fine for about two years now. the non-fouler is pretty rusty on the surface, and there was some carbon build-up inside and on the sensor itself, so my dad cleaned them with paint thinner (used a q-tip on the sensor, and soaked the non-fouler).
car occasionally idles pretty rough when at a stop (almost stalls out at times), but otherwise sounds and drives fine.
help!!
