just looked up the spec on my exhaust using software i have, it seems the small silencer thing that was on my old exhaust but not the new one is another cat. it says its equipped with starting and main catalytic converters! wondering if this is causing a problem with the sensor.

ta, think o2 sensor no1 is just after the manifold

got the gasket from vauxhall but didnt check breathers. there is one that goes from rocker cover to engine block, its been replaced cos it was cracked, what other ones are there.
just remembered... when i put the front section of exhaust on i noticed that there was a slight difference, there was a small silecer on the old pipe coming down from the manifold that wasnt on the new one, would that cause any probs.
the code reader and software i bought seems quite good but as i dont know what the readings should b a lot of it is of no help.

initially it was the no 2 sensor that showed a fault, it looks fine now according to the live data (it was replaced), i put a new exhaust on a few months back so shouldnt b the cat, ive tried an air flow meter but it made no difference.
I have another problem now!!!!!! oil in spark plug holes, happend last year and i put a new gasket in, that solved the problem, i read somewhere that the rocker covers can warp cos there plastic. I love my omega but.....

the first time got codes read the guy just gave me the faults, the ones i posted were from the software that came with the code reader i bought.

Ok, will try that.
The 2 sensors my dealer gave me had different ends on them (but were both 4 wire), the guy said they did the same thing, on some web sites i see them listed as post and pre cat. do you know if they need diff sensors. it was universal ones i bought. the live read out for the sensors are different, No1 bounces all over the place from 0.100 to 0.900 while no 2 sits between 0.300 to 0.600, should they read roughly the same

hi, been havin probs with my 2001 2.2. started with engine mang light coming on, took to garage, one of codes was co2 sensor no2, i replaced both sensors, light still on, presumed it needed a code reader to clear fault so bought one rather than another £28 visit to garage, cleared fault but keeps coming back, this time with "PO170 fuel trim malfunction bank1, below minimum threshold, DTC present at time of request" and "PO130 sensor circuit malfucnction bank1"
the PO170 came back next time with above threshold. any ideas? ta
