EGR Valve Change
 

I am going to bring my '94 in to the delear to have the EGR valve replace. Is there anything else that would make sense to replace, when they are taking things apart to get to the EGR valve?

First off, many people on the forum will tell you to NEVER BRING YOUR RX-7 TO THE MAZDA DEALER. Including me.

You can replace the EGR, but you can also eliminate it on your '94 with the "EGR relay trick" with no ill effects.
