Possibly a coincidence, however, I bypassed the smog pump as it was making a racket with the recommended bypass belt (5.0 EFI). Now the car runs pretty rough puttering and shuddering both at idle and acceleration for lack of a better term. Read previous posts where people have bypassed the smog pump without issue. I did not make any modification to the pump itself IE remove or alter any components. Has anyone else run into issues doing the same?
