I'm new to doing my own work myself. Spent a good bit of time yesterday working on changing my spark plugs. After a few hours, I though I had moved everything well enough to get to the spark plugs. Then gas started pouring out of what I was working on. It appears I was in the area of the fuel injectors. I suggest you don't do that. It does appear that the job is not that difficult if you are in the right area. Just a few things to move (a bar and some hoses that go to your air filter) and you can easily access the spark plug wires/plugs. Hopefully I can reattach all my work from today and have my jeep run.
