stumbling idle after swap
I have done a few months of searchs but no luck
I just swaped a 6.0lq4 into my ss
terreble ide, keeps throwing lean codes, i can't find
a vacum leak, i have ported tb/maf,and 853 heads
the car runs good but has more power than it shows
I dont have money for a tune, just a predator
I fixed the injecetor slop but no luck
any suggestions
