Note sure my flaps are working anyway. A test while reving the engine in neutral from idle either smoothly through the range to 4000krm or blipping through the range does not appear to move the bar. On can only just see a tilt in the bar as though it wants to move but this is all.
Could be that one needs real load and vacuum on the engine to really activate them.
Now a question for anybody to confirm / correct.
When the engine is powered off are the swirl flaps in the fully open position, then move to closed / modulated in the 1K to 2 or 3K rpm range and are fully open again are higher rpm? I have read this somewhere before and have quoted it myself but am now a little puzzled / confused.
Over to the experts.
Just seen this video of the Vectra manifold and it definitely looks like the flaps are fully OPEN in the rest position ( Inlet manifold Vectra C 55210201 - YouTube ) which is good news. i.e
my ball joints are always far left positioned.
hi,
