my rx7's doing alot of misfire and i'm sure that my rx is getting enough fuel so i'm thinking there's something wrong w/ my spark plug or something! what r some good spark plugs to get? where can i get it and how many? thanks for your help thanks!

 

You're asking "how many" plugs you need? Yikes. You need 4. NGKs are just fine ... you can get them at most any parts store or from the dealer. Get two 7s (BUR7EQ ... or BUR7EQP for platinum), and two 9s (BUR9EQ ... or BUR9EQP) ... or just four 9s is fine, too. Make sure you put them in the correct hole ... they're marked on the plugs L & T as are the rotor housings.

 

while youre at it check youre wires ,there is also a ground for the little coil harness check if thats not also a possibillity

 

What do you mean exactly by "misfire"?

 

thanks DK i just ordered 4 9's

 

I was wondering the same thing. Could you be mistaken in your diagnosis and be confusing "misfire" with back fire?
