You can't

There is no such thing as a reset for a misfire condition

You have to diagnose & resolve all cylinder misfires,fuel trim
issues & all 8 emission monitors have to run clear, before you
can be accepted for inspection

You have a class B Misfire that will set a MIL Lamp

You have a class A Misfire that will cause the light to flash
& also ruin your exhaust converter & oxygen sensors
(your problem)

So you have work to do & maybe part with lots of money
along the way

First fix the problem, Spark Plug? Spark plug wire? Coil? Then you will ned a OBD2 tool to turn it off. a Auto Zone store might do it for you. they do have the tools except for California.

SOURCE: Check engine light

A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.

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 wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors. 

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.

Yep!.. Typical with an engine cylinder misfire. Inspect the plug and ignition wire, especially the insulator. If you see a 'christmas tree' pattern on the insulator, that's where your problem is.

I'd have fuel pressure checked, and at the very least, replace fuel filter. Not unusual to get multiple misfire codes due to low fuel pressure, thus starving cylinder(s), and causing the misfire code(s).

Rough idle, acceleration and check engine light went from being on to flashing on and off


Use a ODB-2 meter to read the problem code. That will give you a clue on what to look for next.

Sputtering engine while in passing gear


At 150000 miles the plugs start to fail under hard acceleration the higher compression blows out the spark before it ignites the fuel. Random cylinder misfire causes the check engine light to come on. change the plugs!

I need to turn the Check engine light off, due to passenger/front catalytic converter 2005 nissan xterra


You still fail your state inspection if you turn off the check engine light. So Im sorry to say, that your gonna have to wait untill your new cat gets installed. After its installed you have a few options for turning off the check engine light.
-You can disconnect your battery for a little bit.
-You can take it to pretty much any mainstream auto parts store and they will clear it for free.
Either way you have to complete what is called "a drive cycle" to be able to pass your vehicle inspection.

DRIVE CYCLE
Once problem is fix you complete a drive cycle. Every vehicle is different so this is a general guide.
-There are a certain number of times your vehicle has to be started.
-There is a certain amount of time you have to be driving at different speeds
-There are sometimes a certain millage that has to be reached (ie. drive 75 miles)
If you just drive as you normally do for 100miles (not in one trip) your sure to have reset all the sensers that the state inspection equipment check.

SO IN SHORT
Get the new catyletic convertor installed
Get you 'check engine light' cleared for free at an auto parts store
Drive your car normally for about 100 miles
Get your vehicle state inspection

I changed my spark plugs and afterwards the chech engine light came on. the jeep runs great. what can make that happen?


IT could be something such as a loose plug wire.The best advise I can give you is to take your jeep to your local auto parts store and have them pull the codes out of your on board computer.This will give you an area that you can concentrate on to make the necessary repairs to get your check engine light to go out.

Check engine light is flickering on and off--losing power as I drive--car is a Chev. Malibu


A flashing check engine light indicates a misfire that has the potential to damage your catalytic converter.
I would start by inspecting the area where the ignition wires plug onto the ignition coils. Any burnt coils towers or ignition wires indicate the need for replacement. Your misfire issue regardless of the cause, needs to be repaired before your converter is ruined. Good luck.

when a check engine light blinks it indicates a catalyst damaging misfire. vehicle should not be driven when it is blinking. possible problems for the misfire could be easy like worn spark plugs or more difficult like mechanical issues with valves or bad compression.
