I have a 6spd 04 rx8 with 72,243 miles, things i've done to it BHR ignition kit ( bought 2 years ago) BHR mid-pipe (bought a few months ago) recently changed coil wires and spark plugs. My driving habbit is.....well i love smacking redline a lot (could this be a problem too??)

My car feels like its hesitating between 7500 to 8000 rpms and my engine light flashes at 70 to 80 mph. So i checked all sprk plugs all was ok except for the Trailing thats close to the firewall it was a little blackish. I changed the coils around yesterday to see if the other Trailing goes black (we shall see in a few days).

My codes

P0300-Misfire-still going thru the process i already cleaned the MAF,ESS,

P2259-Secondary air injection system control |B| circuit low-Was doing some reading and i read that this could be the air pump causing the problem. I have noticed that every morning it whines very loud could it be the problem?

P0037- 02 sensor heater circuit low-bank 1 sensor 2- I know for sure my BHR is the cause of this but i never changed my 02 sensors either.

Am i on the right path or am i missing something? my next thing is getting a new fuel pump..........

RX what?

BHR mid-pipe with the converter? If not, eliminate the air pump.

I wanna say that hesitation is the fuel pump not keeping up, but too many things could be the cause.

Im about to delete my air pump but i got a strange question for yall. What does it mean when my car stops doing the bogging at 7500rpms after power washing the engine bay?

Update****

So i remove the spark plugs and behold the black spark plug on T1 this time instead of T2. So i guess my bhr coil is bad.....

RX what?

the bogging down thing after cleaning could be from cleaning off the trigger wheel? maybe it had metal particles on it. idk thats odd.

Another update:

Problem fixed!!!! I changed my coils back to stock and the rough idle is gone the hesitation at 7500 rpm is gone and my gas lasts a little bit longer....lol

Charles told me to send it back and he'll take care of it, so the BHR kit and wires will be sent back tomorrow.....
