Hi everybody I recently cleaned my aos and replaced my hoses for the top mount intercooler after putting everything back I got the lean code. After diag and checking for leaks the only thing I could think of was the pcv valve so i replaced it and no difference. The car feels like it misfires at 2500 rpm but runs smooth for the most part. Today I decided to do a compression test on bank 1 and cylinder 1 came in at 85 psi and cylinder 3 at 90 psi. Is it possible I blew a head gasket?
