Stet28

All checked no problems … got no power to fuel vapour unit do u know would that be in fuse or relay?

I've also replace the battery disconnected lamba sensors still doing the same!

Got a code po171 bank 1 lean on a 04 2.3 petrol (gas converted) changed idle control valve, cleaned throttle control also cleaned mass air flow sensor. My car is holding revs 1100-1200 instead of its normal 850ish when idle. When stopping the revs will shoot up to as much as 3500 but mostly 2500 any suggestions?

Just replaced my plugs for platinum ones and now my car misfires I think the gap size is wrong any help please
