I have a obd2 dizzy, not sure what year, it's swapped into my EF and I did the conversion a long time ago. Well the dizzy died on me. I took my spare 98 ITR one and now I get code 8 and 9. Does that mean my old dizzy is obd2b and the new one is obd2a? Or is the new one fucked up? Cause it was pulled from a running (fired up yesterday) ITR swapped EG with single plug conversion and I can't afford to replace 2, only one. IF anyone knows it would be greatly appreciated.
