what fuel are you using
if ethanol could account for high fuel trims

Egypt shitty fuel man
Ron92 some times Ron95
But here the gas stations even mobil1 / total add some ethanol to the mix to higher up the octane number :/

Update ..
I found a vacuum leak under the manifod and by both side of the manifold base doing that by curb cleaner test it idled higher than usual when i spray there .. so i think the 8 intake manifold gaskets took **** on me .. but when i smoke tested vacuum lines no smoke like there is no leaks .. so long story short iam going that route and i have ordered a new gaskets for the manifold then will keep you guys updated after i change them
