Throttle Response and Failing AOS

[jaykay]

Okay I have just finished about three hours running time: highway, country and gridlock......yah TO has it really bad right now

I pulled the oil filler cap to check for suction and there is enough to hold the spring loaded oil filler funnel until I knocked it against its upward stop....so perhaps approaching the suction force of an old worn out vacum cleaner and I can get a hissing noise happening by hold the cap close. Is this normal suction? I would say no myself...

Also covering and uncovering the the filler funnel a few times disrupts the idle of the engine and one can feel the engine react to the vacum change. Again, not knowing the inner workings of the AOS, it feels like the AOS is packing up. Anyway it's odd that most only see the smoke screen and then they know

How would this AOS condition affect throttle response??
