What do you guys think? (Flashing CEL)
So I have a 2005 Mazda RX8 automatic
BHR Ignition kit
Upgraded 2.0kw starter
KM on body 104,000
on new engine: 25,000
Exoticspeed catback
Whenever the car has just been started from cold (overnight) and I start driving if I go up to 8500-9000rpm I hear some popping sounds from the exhaust and the cel starts to flash and goes away but once the engine is fully warmed and I again go up to 9000rpm the cel doesn't come back on. Could this be some sort of sensor problem?
Mod Edit:
I think you should keep in mind thread titling rules:

He says started from cold, as in not a warm start. He never said he is revving it cold.
Try removing the BHR ignition and put your OEM coils back on. I remember a post a few months ago where someone had this same issue and putting OEM coils back on solved it.

any coil can fail, even the ones supposedly covered in pixie dust
it could be any number of things though, which is why a proper diagnosis is needed rather than dropping hundreds of dollars guessing and then justifying it with excuses on why all new components is always best
