Question about 2006 Mazda 3
Engine was running rough, found water around plug. What can cause this?
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.

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.

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

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.
