Hey, My 88 RX-7 seems to be miss fireing, wich is creating a lil back fire (i think thats how it works). Anyways, I was told that replacing spark plugs would fix my problem. Is that correct? Also should i replace my spark plug wires? and any recommend brands and or websites? If this is indeed my problem.

Thank you,
Zach

 

its natural for rotaries to do that once in a while. Unburnt fuel burns in the exhaust, and boom.
Its kinda cool, I think.

 

even my new 04 rx-8 does that, no biggie

 

It is common to happend durring warm up, and deceleration. If your car does it all the time new plugs are recomend, as for plug cables I use bosh premium, many people use NGK wire also. If you still have the factory cables, it will be a good time to change plugs and cables.
