Taking the AIR pump off will not cause a hesitation. The AIR pump was added to help tailpipe emmissions back in the day. It was just injecting air into the exhaust system to mix with what was just burnt or not burnt by the engine. It was a joke. It was just masking what the engine was really doing.
