Sounds like two problems. P0300 and P0303 are possibly spark plugs. They could be a coil pack but I'm leaning toward a spark plug problem because of the other two codes - they're indicating O2 sensor problems. If the O2 sensors are screwed up, the car reverts to preprogrammed, rich fuel maps that send excessive fuel through the engine. The reasoning is, if the ECU can't trust the O2 sensors to determine how much fuel to burn optimally, it'll pump a bunch of extra fuel through the engine to keep it safe. Having too little fuel (aka running lean) can destroy an engine, so the ECU plays it safe and runs rich (too much fuel) instead. The consequences of rich running are relatively minor compared to lean running, but can and do tend to create excessive carbon buildup on the catalytic converter and O2 sensors, as well as fouling spark plugs.

First thing to do though is to swap the wires on your coil packs and see if you end up with a misfire code for the same cylinder #3. If you do, then it's the plug or wire. If it moves, it's the coilpack. Replace whichever part is faulty. You'll probably need oxygen sensors too, before you can clear all the codes.

SOURCE: the code reads P 306 misfire on cylinder 6. How

A P0306 code means that the car's computer
has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present

Causes

A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

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.

SOURCE: 2006 RAV4 V6 multiple cylinder misfire, VSC, check engine and sli

You need a scanner to pull out the engine light codes.
Use a shopu manual to aid you with the diagnosis and repair.
The slip indicator and vsc light being on means these systems are not working. Once you pull the codes and do the repair and erase the codes the lights will go off.
There will be a code in there for the misfiring.
Good luck and keep me posted.

What do I look for to correct a random misfire code on cylinder 1 and 4 on a 2006 Kia Soreneto 3.5 L? Have a;ready replaced the coil,plugs and wire?


first go over the plugs and wires again. Make sure plugs are gapped correctly, wire boots have good wire connection in the boot top, and the boot is seated correctly on the plug stem. ensure plug wires are soundly seated/connect at the other end. If you still get the misfire code -- get the engine diagnosed -- a sensor or a computer module may be faulty.

Random multiple misfire P0300, P0302, P0304 on 2006 Kia Rio


A competent mechanic will check all probable causes associated with these DTC codes.
Code P0300: Random-Multiple misfire detected. Probable causes:
1. Vacuum leaks, damaged hoses, or improper routing
2. Fuel contamination
3. Ignition system - Ignition module, coil, spark plugs and wires
4. Fuel system
Code P0302: Cylinder 2 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system
Code 0304: Cylinder 4 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system

Be sure the invoice enumerates all of these probable causes as having been checked. Also, some of the replacement parts installed earlier may be faulty.

Kia sorento 4x4 6CL code P0300 P0301 P0302


These are codes for misfires on #1,#2, and random cylinders.

A cylinder will also misfire from the injectors as well as the spark side. If this is a v-6, check for camshaft position sensors.

Check engine light


The first thing you need to do is have the codes read, the this works is the engine computer is always testing all sensors and checking operation when it sees something out of specs then it will turn on the check engine light to let you know something is wrong and then it stores a code in its memory to help you locate the problem, these codes can only be read with a scan tool, there are many auto part stores that will scan the codes and tell you the codes and some will give you a print out of the codes and if you give me the codes i can help you better. for example the code may be PO301 cylinder 1 misfire. this means that the computer sees cylinder 1 misfiring then with some testing you can see what the problem would be. hope this is helpful.

I have a 2005 kia sorento v6 3.5L. the check engine light is on as it has been misfiring now for the last couple weeks. after a scan, using a unversal scanner, it revealed a misfire on cylinders 1, 3, and...


Notice that all of the misfiring cylinders are on the same side of the engine. How was it determined that this is an electrical issue? I would expect further codes to turn up as a misfire code is not very informative. Good luck!
