another sr20det idle problem...

[bamoore]

So I been fighting my s13 blacktop sr20det for the past few months. It has been having a bad idle problem on a cold start I have to press the gas down to keep it from stalling when it reaches operating temp it will idle on its own but it is not smooth. while idling my wide band gauge is full lean i have a aem uego gauge. when I unplug the maf sensor the wide band reads full rich and it idles smooth. I know it goes into safe mode can anyone tell me what sensors are disabled in safe mode or what all happens when in safe mode because it runs great in safe mode? I have tried set timing but when i unplug the tps it dies instantly so idk what timing is for sure. Im open for any suggestions.

Things I have tested
maf (1.6v idle)
tps (.4v Idle)
vacuum leaks (found some and fixed them and did not change anything)
O2 (.03v very very lean)
checked ecu codes (55 was the only code I got)
