When i took it in for emissions it failed on NOx. the vacuum hose that attaches to the upper intake plenum is split and disconnected. i need to know what the size of that hose is. oh i also need to figure out how to get new spark plugs in to #1 and #5 cylinders. neway i try i can't seem to get them out

Sears makes a great swivel spark plug socket for $10 that is invaluable for removing spark plugs from cars with difficult access. Vacuum hoses you can get at the hardware store, just buy 3 feet of all the sizes that look close.
