Spark plug change on 2003 tacoma

I have a 2003 tacoma that I need to change sparks on. It is a 2.7 L 4 cylinder engine. I'm not sure how to access the plugs. Looks like I need to remove a bunch of stuff before I can get to the plugs. Is this a difficult process and can an "average Joe" do the job?

SOURCE: cant find the spark plug location on 2002 4cyl tacoma

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.

Find out what your spark plug gap is, and the size of plugs you require from your owners manuel. Purchase a Spark plug socket for your rachett (also a rachett extension if you dont have one) And a set of Gap Measurers. Pull out the spark plug leads from the base making sure you don't pull on the cable (can damage the lead if you yank on the cable instead of the boot) and then screw out the old sparkplug and check for damage/wear. Set the gap on your new sparkplugs and screw them back in using a torque wrench for the final turn or if you don't have one only hand (do the final turn without using the rattchet just grab the wratchet extension and twist with your hand).

Not a big deal. Realize that the plugs from the factory are Iridium and are good for 100K miles. Assemble the following:

6 Denso IKH20 Iridium Plugs pre-set to .044 gap ($10 each) High Temperature anti-seize (crayon type is $3 at NAPA)
3/8 inch drive ratchet
5/8 inch spark plug socket
4-inch extension
10-inch extension
10 mm socket
12 mm socket
torque wrench (or make real sure you don't over tighten the plugs) new air filter (optional)

Start on the passenger side. Disconnect the air induction/filter assembly by un-snapping the two spring latches on the black air intake box closest to the front of the car. Once these are un-latched, fold the air intake assembly out of the way. Now would also be a good time to replace the air filter if you have not done so lately. With the air intake assembly out of the way, you now have clear access to the top of the valve cover. Along either side on top of the valve cover you will notice three black modules each held in place with one 10mm bolt with a small wiring harness connector attached. These are the coils (one per plug), and the spark plugs are located underneath. Disconnect the wiring harness connector and remove the 10mm bolt. Pull straight up on the coil and it should disconnect from the spark plug. Look down the hole and you can see the top of the spark plug 5 inches down. Using a 5/8 inch spark plug socket with a rubber 'holder' inside the socket to hold the plug, remove each plug. I had to use a 10-inch ratchet extension to provide sufficient clearance. I know it sounds goofy using a standard size socket on a metric car, but it is what it is. I make sure I get each coil back to its original location, but it really does not matter as they are all the same. Since the heads are aluminum and the spark plugs are stainless steel or monel/nickel, you have to be careful not to ruin the threads on the heads. I ONLY remove the plugs when the engine is cold. Apply some high temperature anti-seize only to the threads on the new plugs and install to 18ft-lbs of torque. Slip the coil back in place, attach the connector, install and tighten the bolt and you are done with that plug. Repeat for each plug. Re-install the air intake assembly and snap down the two latches and you are through with that side.

The driver's side is more difficult as there are things in the way. I had to remove one bracket (held in place with 2 12mm bolts) and disconnect a rubber hose underneath that bracket (it just slipped off with little effort - no tools required) in order to provide sufficient room to remove the coils. This is not as bad as it sounds, and I had both removed in under 2 minutes. Now you have access to the coils and plugs and can repeat the process. Go slow, take your time, don't get anti-seize on the plug firing tip, use a torque wrench if you have access to one. Replace the hose and the bracket and you are done.

Total time is 1 hour if you are not mechanically inclined, 30 minutes if you are.

Replace spark plugs as they might have been worn and check the specific gravity of the battery checked. The ignition coil also may be causing the problem.

P0303 cylinder 3 misfire


Hi there:A P0303 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #3.

Symptoms may include:the engine may be harder to startthe engine may stumble / stumble, and/or hesitateother symptoms may also be present

A code P0303 may mean that one or more of the following has happened:Faulty spark plug or wireFaulty coil (pack)Faulty oxygen sensor(s)Faulty fuel injectorBurned exhaust valveFaulty catalytic converter(s)Running out of fuelPoor compressionDefective computer

Possible Solutions:If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hope helps.

Cylinder 1 misfire 2003 chevy impala.. My car started running rough all of a sudden today. like the engine was shaking. took it to auto one said cylinder 1 misfire. what does that mean & what should i...


a number one misfire means that the number one cylinder is no longer working as good as it should or is not working at all. The number one cylinder is on the back side of the engine on the passenger side. 1-3-5 are the three cylinders in the back.

Three basic things can cause a misfire.
1. a bad spark plug wire
2. a bad spark plug.
3. a bad injector.

Remove the sparks plug wire from the spark plug and remove the spark plug. Inspect the inside of the wire and the outside of the plug to see if there is any carbon tracking. it will look like black lightning bolts. If there is any carbon tracking replace the plugs and wires.

Check the spark plug gap. It should be around .060". if its over .080" the plug is worn out.

Check for spark with a spark tester.

the fuel injector is a little trickier.

Start with the things above and let me know what you find and we'll go from there.

1)all spark plugs
2)do a oil change
3)spark plug wires
3)distributor cap and rotor

1.bad gas
2.spark plug and/or wire
3.distributor cap and/or rotor
4.valve adjustment
5.injector
6.off timing
7.ECM
8.bad wiring(power, ground or feed line)

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.
