hey all

my sr20det black top started running flat on boost a few weeks ago. then it started missing when you hit boost
around 3000rpm and will miss the whole way out.
it is missing when its idling sometimes aswel. dont know if its related?

i have done a self diagnosis test and got knock sensor.
ive replaced that and its still missing.
i have also tried new coils and it still missed.
i can unplug my air flow meter and it will still run fine.

any ideas?
