Problem after problem...<p>Now I changed my spark plugs with NGK and now my engine runs on higher rpms and it is a little shaky... I haven't changed the spark plug wires... is it recommended that you change the wires with the spark plugs? Engine is louder than normal.<p>Are there NGK spark plugs which do not work well with our MX-3s? The ones I got were for V-shaped engines.<p>This bboard is very useful! Please, anybody who needs to, feel credited!

You should probably pull all the plugs out and check and make sure there is the proper gap.
If the plugs were gapped correctly then make sure all the plug wires were seated enough.
After you have satisfied the above and you still
have a miss or rough running engine I would suggest replacing the cap and rotor and the plug wires.
Did you have oil in the bottom of the spark plug wells?

Just curiouse, what would that mean is there was oil in on the spark plug?

Double check that the spark plug wires are on the right plugs. If thats OK check the spark plug gaps next.

for starters it would mean the valve cover gasket is leaking. second it would accelerate the end of life for the spark plug wires, and could promote the spark to jump to ground or miss.
