What do these fault codes mean ....
When I got the car it needed a new lambda bank 1 sensor 1 which I replaced , now the emissions light came back on and I had it scanned by a mate today and here's what we got.
  WP_20130422_001 by Chin.., on Flickr  WP_20130422_002 by Chin.., on Flickr Is this all to do with the other lambda that's triggering all the other fault codes ? Ive noticed that today going up hill ive put the foot down and it seemed to misfire a little bit  Any help much appreciated !

Insufficient flow
Insufficient flow is a vacuum leak....find the pipe causing the leak first....then look at resolving the problem with O2 sensors.

Im having no luck finding the air leak
Is it normal for it to cause the performance drop ? As I said earlier the car doesn't seem to pull as well as it did, theres no change in revs or anything it just seems to struggle Is it normal for all the lambdas to poo themselves at pretty much the same time ? Im gonna take it to VASSTECH next week and see what they say.

It seems like im talking to myself but ive found out that the air injection system fault is most likely the secondary air pump, sometimes on a cold start it does sound like a jet for about 60 seconds however that has nothing to do with the performance issue im having. I will take the car to VASSTECH tomorrow and see what they say. I will definitely be getting rid of the cats ASAP.
