Cylinder 4 is misfiring. Take it to a mechanic and have them take a look at it. Im guessing its the distributor, Spark plug, or spark plug wire on cylinder 4

the light is what is called a check engine light it is part of the on-board computer system, the light came on because the on-board computer system has seen a fault with one of the sensor on the car, it could be about any of the 70 plus sensors, you will need to have the codes retrieved you can have this done at most any auto parts store after you get the codes get back with me and i will look it up for you.

Mazda mpv 2004 code p0304


Engine missfire Cylinder #4

P0300 at P0304 Diagnostic Code - Random Misfire
Technical Description
Random/Multiple Cylinder Misfire Detected

What does that mean?
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

Causes
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)
* Stuck/blocked EGR valve / passages
* Faulty camshaft position sensor
* Defective computer

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 help with this (remember comment and rated this).

I have a Mazda 2001 MPV, just had service for o2 sensor and now the check engine light is blinking .


blinking light means engine is misfiring. continuing to drive will severely damage the engine. The O2 should not be related to your engine misfiring

I am getting a P0031, P1512, & P0421 code


P0031 - most likely pointing to a failed O2 sensor (bank 1 sensor 1 is located before the catalytic converter)

P0421 - failed catalytic converter or a failed O2 sensor

P1512 - intake manifold shutter valve is stuck - may be caused by the O2 sensor, but may not

I recommend replacing your O2 sensor first and see what happens
