Message	and new bkr7eix plugs within the last month. All sensors show normal values in datascan including both mafs(I can see each voltage separately and combined on my apexi neo). I'm also struggling to pinpoint a slight missfire at idle. I've also determined recently that the part of the ecu controlling the AAC does not work anymore(brand new oem AAC)...wondering if I'm just chasing my tail with a ecu that's going bad. Also noticed when I use my timing light on any of the coils I no longer get steady light pulses. They are very inconsistent and noticed everytime I get that slight miss at idle the light goes blank. Tried different ptu's and cas's with same results.
