Locate the spark plug cover on the engine.On some Toyota Tacoma engines, the cover is across the top of the engine. On others, it is along the side 4 cyl. Remove the cover to reveal the ignition coils and spark plugs wires. The spark plug wires are plugged directly into the engine and the ignition coils are in the tip of the spark plug wire.
Remove the coil and wire from the spark plug. Twist and pull the plug out of the engine. Remove the spark plug from the cylinder well with a socket extender and socket wrench. Turn the wrench to the left to unscrew the spark plug from the engine.

Discard the old spark plug and apply a coat of anti-seize compound to the threads of the new spark plug.

Insert the new spark plug into the socket. Use the socket and extension to screw the spark plug into place.

Return the ignition coils and spark plug wires to the engine and turn it to lock the plug in place. Repeat the entire the process with the remaining spark plugs.

Replace the spark plug cover when all of the spark plugs are replaced.

Good luck and hope this helps and The spark plug tension may range between 11 and 15 foot pounds, depending on the size of the spark plug. The correct tension is indicated on the spark plug's packaging.

#4 cylinder is misfiring in my 1997 toyota tacoma 4x4. Auto parts store put on machine and got this result. They say that it could be spark plug. Any Ideas. Looses power on mountain.


Possible causes for a misfire:
Spark plug
Spark plug wires
Weak or bad coil
Dirty or a bad fuel injector
Low compression in cylinder
This is a case of testing and process of elimination. Have them all tested to find out which one is the culprit. Change the plug and wire to a different cylinder, if the misfire happens in that cylinder, you'll know it's either the plug or the wire. Without doing any testing, it's hard to say what the cause is.

Plugs


Changing the spark plugs is a pretty easy task. The spark plugs run along both sides of the engine, 1 per cylinder. (3 on each side) You can easily identify them by the plug wires running to them from the distributor. Pop off each plug wire, (1 at a time) and replace the spark plug. Once you have replaced the plug, replace the plug wire. This ensures that you dont mess up the sequence of the wires which determines which cylinder fires at what time in the cycle. VERY important not to mess up the sequence. If you should happen to get the wires mixed up, look online for the firing sequence for your vehicle and engine.

Change sparks plugs on 06 hyundai sonata v6


You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold

2006 Toyota Tacoma Low Mileage or Not...Spark Plug Life


24 mpg on the highway is actually pretty good for that truck. at 48000 miles and being 3 years old its time for plugs, air filter, and fuel filter if available. thats cheap maintenance for now. but if very self conscious, run some fuel injector cleaner first, then change the plugs, because any octane booster or fuel injector cleaner can run the risk of fouling out a plug, by creating a hotter spark then what, normal gas does. the burn is hotter.

#4 cyl misfires/code 304


P-0304 indicates number 4 cylinder misfire. Are you using Toyota parts dept spark plugs? More often than not, non-toyota plugs make the v-6s run poor, right out of the box....
Try this:With the engine running, pull the connector wire off of the #4 injector. Note to see if there is any change with the idle quality. No change? You may have a bad injector.
