Water in spark hole will cause the missing Blow this out and try again. The main concern is how did water get there. Have you been thru a car wash latly or had your engine degreased after a service ? If none of these then things could be more serious

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.

Remove you spark plug leads and see if they are soaked with oil. If so you will have to remove your valve covers and replace the valve cover gaskets. They tend to leak oil into the area of the spark plug holes. You will have to replace the plug wires also. Just replace them one at a time so you will not losthe firing order.Hope this helps.

SOURCE: Check engine is flashing. Checked water level and

No. a flashing check engine light means that there is a serious possibility that the catalytic converter is in danger of getting damaged. If you are losing coolant (and i am guessing that your engine is overheating) you most likely have a blown head gasket or a cracked cylinder head. And because of that you are getting a large quantity of coolant on the exhaust system, which can ultimately damage the catalytic converter.

SOURCE: oli leaking into the piston chambers

I would start with a compression test then move to your valve seals. This sounds like a improper alignment of the ring grove could be your culprit or put in upside down even. Remember to rate my solution

My 02 galant runs rough when put in gear but in idle runs okay it also surges up and down replaced the plug wires


Okay, lets start with the oil you found on spark plugs when you were replacing them. this oil is coming from the valve cover tube hole area, notice the plugs go into the holes in the valve cover, there is a gasket the goes around the top of the tubes and when it leaks it goes into spark plug hole, the valve cover needs replacing .
this will cause rough idle and running problems, after replacing valve cover gasket the holes must be cleaned, using crab cleaner, spray into holes and use air to blow out . this may need to be done a few times to get oil out .
after oil is removed . then remove spark plugs and wipe them clean.
The next step is to find the air (vacuum leak) , you said you hear it around intake tube. check for cracks or broken vacuum line. this leak will cause idle problems and driving problems,

Engine problems


Hi there:
When was the last time the engine was full tuned up? This sounds like a classic ignition misfire! They usually go bad under a load like under acceleration, but can be noticeable at any time.


It is very important to have your engine equipped with good tune up parts or you may be causing damage to other components of you car like the catalytic converter which can be expensive.


Possible causes:

Ignition misfire causes by any bad tune up part and or ignition coil or coils.
Bad spark plugs, spark plug wires and cap and rotor (if equipped)
Wrong tune up parts spark plug, wires etc...


The quickest way to check the ignition components, is by looking closely for leaking secondary voltage. Visual look at all the tune up parts to see if you can see any sparks coming from any of the wires or coil (or coils) when the vehicle is running. If not, you can put your hand on the coil/coils and wires when the engine is running and see if you feel any small voltage leaking form the tune up parts.

It will leak secondary ignition voltage from the tune up parts caused by high resistance from carbon tracking if they are bad. This is very common if the tune up parts are not changed regularly!


If any is found, the tune up parts are simply bad and will need to be replaced! If none is found than you can spray a mist of water on the tune up parts when the engine is running and see if that causes the engine to stumble or run rough at all. Again, if it does, the tune up parts are bad and will need to be replaced.



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

04 mazda 3s 2.3l. the emgine misfires randomly but frequently. does have power loss and poor gas mileage. there is no check engine light and had recent sparkplug change with motorcraft platnums and oil...


I have changed plugs using the platinum plugs and the problem don't go away. These plugs can make a car run worse in some cases. I have found it best to use the OEM or a step above on 4 cylin and 6 cylin engines. The Plats work fine in 8 cylin engines. You could also have a bad plug wire. The plug wire could be jumping spark. At night, open the hood, start the car with lights off. Look around the plug wires for sparks jumping. If a wire is bad, the spark is leaving the wire and grounding itself to the nearest metal causing rough engine idle and misfire.

Pull the spark plug wires out one by one and check for oil on wire. Sometimes the valve cover spark plug hole gaskets leak oil into the spark plug hole and causes a misfire. If oil found clean with brake or carb cleaner and blow out with compressed air. also when car runs bad listen under hood for snapping noise this would be spark escaping to ground somewere. In a dark garage you might be able to see the spark.

If you have this problem its possible you got water in the main harness conector on the top middle firewall. I used a hairdryer and put some silicone on mine to help. Also, the coils on the sparkplugs and the rubber around the spark plug can easily fill with water so check all plugs and holes.
