problems problems

my gta has started to run lumpy as if its missing and the afr gauge is reading 17.8 even under normal driving conditions its reading 16.7 so i thought i would be daring and boot it in 1st and 2nd and it dropped to around high 12s low 13s any ideas what could be causing this

That's fecking lean Dunno with all your added bits ,Dastek Lamba ?

it has seem to have sorted itself its going to noble on monday for a final setup,330cc injectors,fuel reg etc etc so im hoping it might play up when they have so they can sort it
