the thing is it only sputters and bogs when i turn the air on .. and the sputter i am tlking about is a constant sputter ... around 1500 rpms when air is on it hesitates to switch gears ... but when air is off it doesnt do any of that. I dont know when im driving down the inerstate and i want to to pass someone i can stomp it and get around fast .. if it were the intake (dont know if this is right) but shouldnt that not work ??? When i go up hills without air on (steep hills) it doesnt switch to a lower gear until maybe the top ?? Also i have noticed my oil pressure drop it stays at about 20 while idleing now and it just started doing that like last week .. it rises to about 39 and 42 if i gun it ... shouldnt that be higher ... ?? maybe that will help more

i know the intake manifold is $$$$
