I have an 04 RX8, 56k miles, new plugs, and recently during hard acceleration I've noticed popping noises and it will miss and then back to normal, no CEL. Mostly happens when the A/C is on....

Any suggestions?

 

coils?

 

Did you ever find out what the problem was

 

There might a problem with your ac compressor.

 

90% of the time it's coils and/or catalytic converter.

Guesses aren't helpful.

 

I think he may have fixed it within the last 6 years or so, but I'll bet it was probably the fuel pump.
