That should help.

I just use the BUR7EQ/BUR9EQ spark plugs and OEM replacement wires. You can get some Magnecor wires if you want.

You can check http://www.mazdatrix.com/ignition.htm for more info.

 

Change out the fuel filter and perhaps the O2 sensor too.

 

The full tuneup proceedures are listed in the Factory Service Manuals. You can download them from the links in the FAQ.

What it doesn't mention is that you should check all the fuel lines for leaks and verify the pulsation damper (see Archives) is not leaking.

Also take a look at http://www.aaroncake.net/rx-7/newowner.htm
