Have fun pull all coil packs in that van.

Pull and inspect for crack body if not then pull boot and spring off then add dielectric grease on both side of spring then put back in there.

And keep driving van with that issue will ruin your cat convertor fast. I drove mine for like 200 miles later to find 2 spark plugs hole were full of water on #5 #7 cylinders. After that mileage never went up until I remove cat convertor it was plugged fast.

Inspect pcv hoses. The pass side rot and create a leak.

Not too bad if you have small hands.I havnt done them on a van,may be easier because the dog house comes off.Probobly will not be easier because that would be too easy.I think all you need is a 1/4 " ratcet with some extensions,a 1/4 " swival and 8mm,10mm sockets. You have to unplug the injectors to get some coils out.I would put some fresh spark plugs in there while your at it,anti seize them and make sure they are tight.These motors are known for blowing spark plugs out and taking the threads with them.
Put some dieleletric grease on the coils when you install them to keep moisture out.
Might want to look at your exaust manifold bolts also as they are probobly rusted to the point of breaking soon.

How many miles on the plugs? We just had a truck at work doing the same thing and plugs and boots fixed it
