so i've had my rx8 for almost a yr now. the power was pretty good till the last couple of months. i felt the engine has lost some significant power, it just doesnt accelerate the same anymore. as of now i have no codes but it has some misfire at high rpms and the check engine light flashes. so i was wondering whats going on with my 8 and hope i can get some help. Thanks!

things i had done with the car so far

-replace alternator due to a bad diode
-checked compression in january and they were all in specifications

 

You could try searching around the forums as well, other people have these problems and it saves you time by not having to wait for people to respond to you...


Guess I'll start with the obvious... last time you replaced coils/plugs/wires?

 

Check your cat,

 

i dont have any codes for the cat tho. should i just replace it with a midpipe?

 

Did you have any codes?

 

no codes. replaced the plugs last december. i also inspected the coils and wires they were all within spec

 

please explain your inspection process to the plugs and wires.

If you had any CELs in the past, but have disappeared, they are stored in memory.

 

i used my meter to check for resistance. they were all in spec so i dont know what else could be the problem
