Changing out spark plugs on a 1994 Toyota Camry 2200 4 cylinder

I read the instructions in my book that says to pull the boots off of the top of the manifold and change out the sparks. But the boot has a long (breather tube?) on it. When I look down into the cavity it doesn't look like the top of a sparkplug. Is there more to take off or undo? Also what size ratchet would I need? I don't want to ruin anything. You've probably answered this question before but I'm sure with the spring tuners working on their cars another mention would be very helpful. Thanks!

    Hi Mike,

    Thanks very much for the info. Greatly appreciated. My 94 has 310K on it and runs like a dream. The only real issues I have is when the car is in D at a stop. The car vibrates a bit.. nothing too annoying. I push the drive into N and it's smooth as silk. Some research tends to lean towards changing out the dogbone engine mount. Is that a DIY? Also, the dash lights on the D N R don't always light up. Mostly R. Anything I should worry about? Cheers!

    Hi Mike.

    Thanks again. The only issue I forgot to mention is that when the R light doesn't come on neither do the backup lights. Once it lights up the backup lights come on. Connection somewhere?

    Thanks FRC. Hopefully I have a 16mm spark socket. If not, shopping trip. Something else. I replaced the hood struts on my Camry as they wouldn't hold the hood up. On the strut closest to the driver's side there was a connection from the strut to a screw on the body. I just cut it as it just looked like a ground and the new strut didn't have a spade clip on it to attached the line. Is that a problem? I haven't experienced any issues, but sometimes what you don't know can hurt you.

There are nothing else need to come off before you pull the boot from the top of the cover. the tube is not a breather , it is just a extension of the spark plug wire. use 16mm plug wrench with extension. (insert in side of the socket holds the plug when you pull it up). you can't get the plug out with regular socket wrench.

No there will be no more disassembly necessary than that, what you see is the top of a spark plug, may not look that way, but you will need a 3" extension and im not sure if it is a 5/8 or a 13/16 socket size, but one of those two for sure, when you install the new plugs, make sure that they go in straight and be careful not to overtighten them, if you strip out the threads, your going to have a hell of a time repairing that, GOOD LUCK

    The Lights are just that lights there is nothing that it is going to hurt unless it bugs you too bad, the 94 camry is an easy car to work on, i would imagine with some precautions and common sense you could replace that dogbone yourself, i would also investigate the motor mounts and transmission mounts, i know in my 94 corolla they went bad at about 250k, so it maybe time, it caused the same problems yours has, having a small vibration. overall great running car.

I cannot find the spark plugs on my camry !!!

First, you didn't mention which engine your 1994 Toyota Camry is equipped with. (This is really MUST-KNOW information if you want help with fixing your car.) There is a 3.0L V-6 engine and a 2.2L 4-Cylinder engine. Two TOTALLY different animals! I'll just take the extra time to answer for BOTH of them....

If your Camry is equipped with a 3.0L V-6 engine, You cannot find the spark plug wires because there are none, That engine is equipped with Coil On Plug (COP) ignition. The coils on the left bank (the side of the engine near the radiator) are located under the plastic cover on top of the engine. The coils for the right bank (the side of the engine near the firewall) are located under the upper intake plenum. The plenum MUST be removed to access them. (this is also required to replace the spark plugs.)

If you have the 2.2L 4-cylinder engine, the wires run down the center of the valve cover and the boots go down through the valve cover to the plugs. The other end of the wires attach to the distributor cap at the rear (drivers side) of the engine.

I'm working with a 1994 4 cyl. 2.2L Camry. It suddenly started running rough. Like a bad miss. Replaced the plugs, wires, dist. cap and rotor change. There is fire going to the plugs...

it may be an injector problem on that cylinder, the injector could be blocked or the wiring or connector is faulty.....hope this helps......cheers.

How do u change the spark plugs on a 1994 toyota camry

Start with a cool/cold engine.

Four cylinder: Remove spark plug wire boots (four in a row on top of the engine). DO NOT PULL ON THE WIRE only the rubber top. Make sure the wires are numbered, if not, number them. They MUST go back to the same hole they came out of after the new plugs are installed. Remove the spark plugs with a 16mm spark plug wrench. Install new plugs (any auto parts store can tell you what your options are here): Start threading the new plugs by hand so you don't cross thread the engine head by accident. Then complete tightening them gently. Spark plugs are supposed to be tightened to a specific torque: 13ftlbs in this case. If you choose to not use a torque wrench do not overtighten the plugs. Reinstall boots securely.

6-Cylinder: Remove engine cover, if present. Disconnect the six connectors on each of the ignition coils. Remove each of the six ignition coil bolts and then remove the coils by pulling straight up -- arrange them so that you know which goes back where. Remove and install the six plugs as described above. Reinstall the ignition coils with their bolts (torque: 69 in-lbs), then wires. Replace the cover.

I need a spark plug wiring diagram for a 1992 Toyota Camry, 4 cylinder, 2200 motor.

I believe your firing order is 1-3-4-2. You may see a number 1 on the distributor cap on this vehicle. That is the #1 plug wire. The wire hole next to that would go to spark plug 3 etc. Easiest way is to change wires one at a time. Hope this helped.

The solution is for a 4 cylinder
Find the camshaft cover, located at the top of the engine.
There yfind 4 square rubber objects with wires connected to the coils, pull them up, inside the exposed tubes you find the spark plugs.
You will need a 5/8 spark plug socket on an 8" extension with a ratchet to remove the spark plugs.

If you still get troubles, buy the repair manual here

There you can find detailed instrucions with pictures.
