Default 2001 Montaro Sport 2.5

I just got 8 failed emission readings from the inspection station; P0421, P0101, P0107, P0111, P0154, P0174, P0401, P0403

Does anyone know of any recalls, or what any of these codes mean - any idea what the price will be associated in fixing these items.

Thanks

Rich

p0421 is a cat converter code,p0101 is a mass air flow code,p0107 is a baro sensor code,p0111 is a air intake temp sensor code,p0154 is a o2 sensor code,p0174 is a fuel trim lean code bank2,p0401 is an EGR insufficient flow code,p0403 is a EGR control circuit code.when a vehicle comes into our shop with that many codes in it, we automatically clear all the codes and then see which ones come back. then you start the diagnosis. the ones that come back are whats called ACTIVE codes, meaning the problem exists all the time. you go from there. the p0154 o2 sensor code has a T.S.B and requires a reflash for the pcm for a fix. dealer only fix. the EGR ports on the intake are probably clogged up causing those codes. the p0421 usually means the converter has deteriorated and is not performing to factory specs. usually has to be replaced. the other ones we dont see very often.
