Spark plug replacement.

I went to replace the plugs and wires on my Tucson, 6 cylinder, and realized that 3 are close to the cabin and seem impossible to access. How does one replace these without removing the engine?

05 Tucson won't start with new battery

Try choke start. Check wiring to spark plug. And clean gap between spark plug contact points.

1998 chevy blazer - replaced the distributor cap 4x because of loss of power/misfire when accelerating. Post for plug #6 at cap is always discolored when truck runs bad - replacing cap corrects the problem...

It sounds like you have the old carbon filled spark plug wires on your blazer instead of the wire ones. If I am right, then the #6 plug wire needs replaced. If not that, then go to the better spark plugs when you change them AND make sure you take a good look at the #6 plug closely to find out if you are getting either a carbon build up (which the better hotter plugs would correct) or if it is oily which might mean #6 cylinder is going to need a ring job.
Hope this helps

If its running fine than you did it right.

if not the coil towers will be labled for the cylinders they go to.

coil should be labeled

cylinders 1-2-3 are on the passenger side
cylinders 4-5-6 are on the drivers side.

Knocking sounds coming from either the camshaft or timing belt area the the check engine light is on and throwing a code for a miss fire on cylinder 6 does anyone have any ideas?

a miss fire would mean a bad coil for #6
if you have a coil pack all with all 6 plug wires need to replace it.
if your coil pack has 3 or 4 coils need to replace just the one with # 6 plug
wire in it. most have 2 plugs per coil.

Replacing spark plugs

Not exactly sure what you need?
Standard Rules:
Use a Spark Plug Socket to remove and install Spark Plugs.
Replace (remove) one Wire at a time from one Spark Plug.
Replace One Spark Plug at a time. Use Anti-Seize Grease applied moderately to the threads on the new Spark Plug.
Using a Socket (with a extension) START all installations using your hands. This prevents cross-threading and stripping of the threads inside the Heads.
Standard Torque 15-20 ft-lbs.
Replace the One Wire connection to that One Spark Plug.
Replace that One Wire connection to the Ignition Coil.
Go onto the next Spark Plug using the above Rules.

For the 3.4L V6:

Duraspark Type Plug Wires
The spark plug wires used with the Duraspark type ignition system are 5 / 16 in. (8mm) in diameter to contain the higher output voltage. There are two types of wires used in this system, and some engines may have both types installed. It is important to properly identify the type of wire used for each cylinder before replacements are made.

Both types are blue in color and have silicone jacketing. The insulation material underneath the jacketing on some plug wires is a silicone layer separated by glass braid. The plug cable not incorporating the silicone layer is used where engine temperatures are cooler and are identified with the letter SE with black printing. The plug cables with the silicone insulation are used where high engine temperatures are present. These cables are identified with the letters SS with white printing.
Each spark plug cable, if original, is marked with the cylinder number, model year and date of cable manufacture (quarter and year). Service replacement wires will not have cylinder numbers, or manufacture date.

On any vehicle equipped with a catalytic converter, never allow the engine to run for more than 30 seconds with a spark plug wire disconnected. Unburned fuel in the cylinder may ignite in the converter as it is exhausted and damage the converter.

When removing spark plug wires, mark and tag the individual wires. Grasp, then slowly, twist the insulator back and forth on the spark plug to free the insulator. Do not pull on the wire directly as it may become separated from the connector inside the insulator. Special tools are available which can help ease plug wire removal, and prevent damage to a cable.

When installing a new set of spark plug wires, replace the wires one at a time so there will be no confusion. Start by replacing the longest wire first. Route the wire exactly the same as the original.

Spark plugs

Firing order for the 4.0L 6-cylinder is as follows:


As for the spark plugs, it looks like the Autolite AL 985 plugs are what you need. If you are going to replace the plugs, might as well also replace the plug wires, the distributor cap and rotor (if you have those, I dont recall which year they went to the distributorless ignition).
