HI, first up looking around the UIM i saw a few of the vacuum attachments unplugged? You can see one in this picture, Do other people have this pipe unplugged to? i would have thought that any unplugged vacuum hose would make the car stall or idle roughly,, my idle is pretty good..



the other problem was when i removed the ducting for the filters i noticed that my radiator hose was all constricted.. heres the pic..



when i opened up the AST there was a big sucking sound and the radiator pipe inflated to its normal size?

 

its normal for them not to be used, some are for different trans. if you do a search for the vacuum diagram you could double check to make sure
