Question about 2002 Toyota Sequoia
Misfire means the crank sensor thinks that piston is not contributing to the power of the engine. First replace the spark plug. If it still misses, check the compression in that cylinder. Many parts stores will loan you a compression tester. Take the plug out, screw in the tester, remove the middle ignition wire from the distributor and ground it to the engine. Then crank the engine through a couple of revolutions. Read the meter--it should read at least 125 psi. remove the tester and replace the plug and gnition wire to the distributor. If compression is low, this may be caused by a burned valve or blown head gasket. Consult your mechanic on how to fix. If compression is OK, replace the ignition wire to that cylinder--you may have to buy a complete wire set. These are the normal remedies for a misfire on a single cylinder. If you have questions, please let us know.

As mentioned above, confirm that the spark is in good condition with no oil or carbon deposits and the electrode must be in perfect condition. The spark plug must have a gap of 0.8 mm or 0.031 inch. Make sure you set the gap, even in brandnew plugs. Then check the coil by removing it, but place the plug in it while the coil is outside, unplug the injector connector and try to start the engine, when the coil is good you will see the plug generate sparks. If that is okay, then you need to confirm the injectors are ok, you can check the resistance thru the leads or remove it and provide 12v power while outside and in a container with gas see if it actually sucks gas and sprays it at the other end. The wiring going to the injectors might be also damage, you should checl for continuity from the ECU to the i jector connector to confirm there is no short. The fuel pump confirmation is next, along with a few more components, but all else affect not only one cylinder but many.

Probably the individual ignition coil on the problem cylinder. easy to change with a 10mm socket. unplug connector pull out coil. I'd change the plug also. All of them if they are near replacement time. Don"t scrimp, get the iridium plugs that it calls for. Some other items may be in the way. If they are, you make the call if you can do it or need a mech to do it for ya.Good luck

It can be issue with spark plugs or faulty spark plugs. Also
get the compression test done for cylinders. If any of cylinder shows low
compression then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.
