Diagnostics test Result help

[mulldog33]

Hey guys,

I just done the self diagnostics test after having a surge problem with my car that i think has something to do with the air flow meter.

Anyway after readig posts about how to do it i tried but am not sure about the result.

Its a 93 R33 GTST. The ECU has one red led light only.(is this normal??) after putting into diagnostic mode i Kept Getting: 2 flashes then a pause then another 1 flash.

Does anyone know what this means????

Please help me, I have no idea what this means, Im sure its a simple answer????

Thanks heaps,

Brendan

Sounds like a Code = 21, which is an ignition (spark) problem.
