It's *not* hard....at all. It *is* time consuming - because I remove the wiper cowl and intake plenum. It's *not* something you need to pay someone else to do - as long as you can read your service manual, not difficult at all. *DO* be careful with the vacuum lines as you mark and remove them - they are very brittle. Ideally, you'll have at least all day to dedicate to this task.
IMO, removing the intake plenum is wise because it gives you a chance to inspect the valve covers - all the bolts on my rear valve covers were way loose, and probably the real reason it was leaking, but I went ahead and replaced the valve cover gaskets as well. Many folks complain that removing the wiper cowl and intake plenum are too much work - but it makes access a breeze and you can actually torque the spark plugs properly when you re-install them. And you can easily check the torque on those rear valve covers.
I'd far rather spend my time removing a few extra pieces than waste a lot of time trying to get that perfect angle while reaching up in a cramped space with less-than-ideal leverage.

So, in the whole bang for the buck laundry list of things to do or have done, I'll replace my own brakes, oil, shocks, struts, filters, bushings and even head gaskets, but I'll gladly pay someone else to do the spark plugs (unless of course I'm doing them at the same time as the head gaskets, which I'm not). Go figure.

I get criticized often for turning down OT so I can work on my vehicles.
I am reminded that in most cases the OT will more than pay for someone else to do the work for me.
It's all about the complexity of the job. Some things are just to much hassle.
If it's a straight forward thing that you can see progress, then I don't mind doing them ... but if it's a hassle, forget it.
I learned long ago that such things like exhaust pipes, even if all preformed are TOO much of a pain.
You need to remove the wiper/cowl assembly. Makes it much easier to reach the back plugs.

I have a 2000 T&C LXI with all wheel drive. I found it not too difficult to change the plugs and wires from below. I used a lift but Drive on ramps will work too. They are tricky to see/feel, but it can be done fairly easily. I am 6'2, my arms are long, but my hands are big.
While your there check your P/S pump and lines. If they are rusty, replace them. Also check your belt and tensioner. The pressure hose is avalable in the aftermarket now, about $20 vs. $60-$70 at the dealer.
Since I didn't see it mentioned other than mopar or napa preferred...
In having a tuneup done on my 1999, mopar wires were important.
The other two that were installed(Bosch and another brand I don't recall) sent feedback into the stereo. Static noises both on both AM/FM and CD.
Replacing with Mopar wires resolved this.
if anyone is interested I did a posting on this a few months ago with a bunch of pictures.
a bit of a challenging job if you are not a professional mechanic. however, the weekend mechanic can do it.

anyone who has a question or wants some help go ahead and email me.
meanwhile ... back to work on the '92 caravan ...
