Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.

Although may things can cause this issue,I would look at the items above first.


Please rate this a blue fixya

SOURCE: misfire and poor acceleration in kia sportage 1999

Poor acceleration would be from the misfiring, so start there. As Ruben said, do a code scan for trouble codes. Does it misfire all the time, or only under acceleration? Use insulated pliers and pull the plugwires off one at a time (and replace) until you find the misfire. The misfire will not change engine speed when removed, but a plug that is firing will slow the engine noticeably, maybe even stall it. When you find the misfire, it may be a bad sparkplug, bad plug wire, or the coil for that cylinder.
Be careful with the plug wires. Before you begin, loosen them from plug and reinstall, so they are easy to pull off when engine is running.
Good Luck.

SOURCE: 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 came on last week. They said it was the heated oxygen sensor. I had it replaced and today the light is on again. The code at Auto Zone is P2096 and P0300. It says P0300/P0301/P0302...


Yes a misfire could cause a false 02 code. As far as why it's misfiring could be a plug and wire issue but hard to say without looking at it

2002 elantra cyl 2 random misfire


Hi there:A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

For example, a P0302 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 #2; same condition in P0301 - cyl #1, P0303 - cyl #3 and P0304 - cyl #4.

A code P0300 (or 301, 302, 303 or 304) may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer

About your 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.

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.


Hope this helps.

Code po300


Hi Joyce:
P0300 - Random/Multiple Cylinder Misfire Detected
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.

A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

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

A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)

Faulty camshaft position sensor

Hi there,

A P0300 diagnostic code indicates a "random" or "multiple" misfire.


Unfortunately, P0300 doesn't tell you specifically which cylinders are mis-firing, nor why (code P0301 would indicate cylinder #1; P0302 would indicate cylinder # 2 etc). This means there could be an issue with any number of components/circuits relating to the ignition/combustion circuits.


I would recommend you check for the following:

  • Faulty spark plugs and/or HT leads
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor

Sometimes the underlying cause of a random misfire is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold, unmetered air getting past the airflow sensor, or even an EGR valve which is stuck open.



Hope this helps...
