4age 16v running roughly - diagnostics shows unknown code

[Ryo]

Hello,
I seek help understanding in 4age self diagnostics what means 2 quick pulses (check engine light) followed by pause and after that 8 pulses follow and it repeats. The error code is not in the 4age manual. Anyone having some experience what such code means? My ae86 with unmodified 4age 16v was running fine until recently now it idles roughly i can write in detail lot about it but what i would like to find more about is this error code maybe it has somethig to do about the issue i am experiencing.
Thank you.
