i can understand the fuel trim fault, but not the bank 1 bit.
fuel trim controls injector duration whereas bank 1 usually refers to the DIS pack

the distributor pack.
all i can think of is the charcoal cannister when you mentioned carbon filter.

Bank 1 is cylinders 2&3, although i think that description is wrong as in my fault codes book fault code p0170 refers to the lambda sensor. that could also give the symptoms you are describing.

when i bought the new lambda sensor it was a diferent style to the one we removed, still a single wire one but had a thiner longer head instead of a short stubby one could that have anything to do with it??

impossible to say really.
if i were you i would unplug the lambda from the loom. this will cause the ecu to replace the missing signal with a pre determined one. run the car (em light will be on) . then clear the fault codes. read them to make sure they are clear, then plug in the lambda. run it again and see which codes come up. if the code 0170 re-appears its likely to be lambda thats causing it. also look at your plugs, post a pic if you can as they can give lots of clues about whats going on. (rememer which plug is from which cylinder tho)
u2u me and i might have something of interesst for you.
