clink on the above link to YouTube and view many vids about your car. I recommend watching more than less of them, everyone has there own hacks for work used to called "licks and tricks" 71 yrs old

depending which one is being replaced usually not bad. however some require a frost plug install tool that has a flex able head to get into tight spaces. it maybe best to have a shop replace it as it makes a mess.

You first have to remove the ignition coils or plug wires and then remove the bolts holding the cover to the cylinder head. Discard old gasket. Clean gasket channel of any oil and install new gasket to cover taking care during assembly not to disturb gasket when placing cover back on cylinder head. The rear gasket is much harder to change as the upper plenum must be removed to access this cover. You should have some knowledge of engines if you are going to atempt this repair on your own

Panels usually push on with plastic clips or screws,some screws are hidden behind push in plug covers.

The speed sensors are on the side of the trans that faces the front of the car. They are about midline height, with one of them near the seam between the engine and the transmission, and the other near the very far end of the transmission, basically on either side of the vertical shift rod. They simply unscrew, after lifting tab and removing the electrical plug, and screw back in to about the torque of a spark plug. They look very similar to one another.

Yes that is one of the first places to start, obviously a full tune up would be desirable, but your probably trying to avoid the costs.
1.New spark plugs
2.Check the resistance of each spark plug lead, as long as all the resistances are similar they willl be ok. if any are quite a bit different change the whole set
3.New air filter element.
4.Change the oil and filter..
5. Possibly a new fuel filter.
the timing and the fuel mixture should not need to be touched

Should be located close to the oil filter. It will screw in like a spark plug. It has a harness plug. Easy to change, save yourself $70 in labor. You will need a fairly large wrench to remove

Depending on the tightness of the socket fit and the engine, carefully pull the spark plug out of the bore



Hope this helps some...best that I can find!

You'll need to remove the intake plenum. From there you can access the plugs and wires.

Method of opening air cleaner --- there are no bolts to remove
