DIY PGMFI Diagnostics - Code 43 FSS

[dsp26]

Hi John,

your right this one is tricky and i'm in need of your skills for this one...

- getting this code now 1 week after rebuild with cams
- had O2 sensor issues prior to rebuild and was replaced during
- CEL comes on 5 or so minutes of idling after driving regardless of how i drive the car
- reset ecu and will check again tomorrow
- genuine honda fuel filter is less than 5000km old
- adjustable fuel pressure regulator set to 38psi vacuum on as per honda specs (45psi vac off i think)
- running the p30-j02 rom but never caused an issue in the months i've been using it
- run on both bp 98oct and mobil synergy 8000 (98oct)

now my question is, is this code solely related to hardware failure or can be due to starvation issues also?

i doubt its a starvation issue though as i'm only on about 136whp..

Thanks in advance
