code 0170: fuel trim bank 1 malfunction
possible causes: intake leak, AIR system, fuel pressure/pump,

Just means the mixture can't be managed correctly because the ECU is trying to change the amount of air and fuel and the results aren't correct.
Basically something on the fuelling supply side or air - usually a leak - would cause it.
First thing to do is to idle it and spray brake cleaner around the intake, if any is taken in the engine should rev up because it's more flammable, which will give you clues to the leak.
If that doesn't work, fuel supply, filter, pump etc. are the next things to check. Poor quality fuel can also sometimes cause it.

lambda is basically an oxygen sensor... when i had the oebd kit on mine last night we went through all the options on it and lambda came up... its flicks between rich and lean as it tells the ecu more fuel, less fuel...
not 100% but could have something to do with it, would check the above first though, id go for air leak tbh mate
