does anyone know what the pressure behind the throttle bodies should be at idle?
i assume you check it by attaching a pressure guage to the pipes above each butterfly valve, would a mechanical boost guage do the trick?
does this have to be done only when hot? as my idle is very lumpy at the mo when warmed up (rises and drops constantly between 1600 & 1200rpm) but its ok when cold so would be easier to check then.
any hep welcome
