Disclaimer: I am not a mechanic. I am a DIY'er and I have done this in my home garage.
If you have a basics mechanics tool set you should be able to complete this in a couple hours on the weekend. I don't have the exact nuts and bolts to remove, but I took the least as I could. The issue is the intake manifold removal...
- metric socket set with varying extensions
- rubber mallet or hammer and a piece of 2x4
- bungee cord with hooks
- digital camera - take pictures to refer back to later, just a backup
- Spark plugs
- Spark plug wires - get the good ones, cheap go bad very quickly(see my other posts on hesitation)
- paper towel - used to plug manifold holes
- plastic cups - used to keep track of all those nuts and bolts
- gasket? I don't recall if I needed one or not?
1. shop vac as much crud off the engine that you can
2. have work bench or table nearby with tools and supplies
1. Look over and study the compartment and determine what bots/nuts need to be removed. I tried to leave as much attached as I could, but you may need to remove them later .
2. Start taking pictures of engine from all angles, closeups are best
3. From front to back, start removing nuts/bolts and put them in cups and mark appropriately. These cups should be arranged on your workbench in such a way that the first to come off is the last to put on.
3. When you get to a point where you think you can remove the manifold, give it a few taps with a rubber mallet to loosen a bit. If you don't have a rubber hammer, use a reg hammer with a piece of wood. You should now be able to lift it off the block. Be careful not to get dirt in the manifold holes, and stuff holes with paper towels. Since their are still connections from other parts of the compartment to the intake, you will not be able to take it out of the compartment. Use the bungee cord and wrap around the manifold and hang from the hood. You will need to adjust the cord to balance as best as possible.
4. Should be able to remove wires and plugs and replace them.
Hope this helps and good luck!

If the car is missfireing, don't try to patch it one plug at a time. go ahead and replace them all at once. It will save you 5 more cylenders to hunt later.

this engine is turned sideways in the engine compartment. looking at the front of the engine, where belts and pulleys are mounted, the odd number cylinders are on the left, the even to the right. starting from the front of the engine, counting towards the rear, the cylinders are numbered 1, 3, 5 on the left and 2,4,6 on the right. remove the spark plug in the number one cylinder and place a peice of tissue in the hole. now crank the engine in very short bursts. as soon as you hear the engine crank, let off the key. check for the tissue to fly out of the spark plug hole. once the tissue flies out, the number one piston is up. now you need to take the cap off the coil, and see where the rotor is pointed. hold the cap over the rotor to see which terminal lines up with the rotor contactor. connect one end of the plug wire to the corresponding terminal, and the other end to the number one cylinder spark plug after it is reinstalled. from here the coil terminals are numbered in a clockwise direction. the firing order for your engine is 1-2-3-4-5-6, so you just connect one end of a plug wire to the number two terminal, and the other end to the spark plug in the number two cylinder. repeat this procedure for the remaining wires,
