Parker:
You DEFINITELY need to have no leaks in this rubber hose (or any others
between the intake valves and the AFM). Otherwise you'll get unmeasured
air (false air, the Germans call it) into the system and not have fuel
to go with it. (too lean.). Perhaps the two clamps are different size?
Or, get a different clamp or put a shim between the clamp and the hose
temporarily.
