Re: 1968 GMC 250 Inline 6 4.1L Chugging
The A.I.R. system is not the cause of your problem. Anyone removing the system did it because they either didn't understand the function or didn't like the buzzing the pump made. Or maybe some other reason that I don't know about. But it won't cause your problem.
