FP seems low to me too and yeah it could be your AF for sure.

 

what kind of fuel pressure do you guys run? mine is return style now and it runs around 50 at idle too. then rises from there as vacuum goes away.

 

wot in park it gose to 65 pressure check engine light finaly came on system too lean bank 2

 

there weared part is that i drive like at 60mph for like 10-15 in a straght rd normal driving and it kinds of gosed away but as soon as i park it and turn it on 10 mins later back to studdering and stuff

 

sounds like bank 2 o2 sensor died.

 

it must be the wireng or something cuz i installed 2 new sensors and nothing

 

What is your A/F ratio? Are you running cats? If not are your rear o2's turned off?

 

no cats rears turned off at idle it would go to 20 and my tuner was telling me some thing about that but dont remember and i havent talk to him at wot i dont remember wat it was but i got to get it tuned at a perfect a/f ratio and all this stumbling happend after we finish tunning

 

sounds like a lean spot( ve,maf,etc.) on tip in when bearley stepping on the accelerator

 

cleaned maf check 02 wireing its good still same problem cepedas said that wen he was scanning it that the map sensor would spike all mof a sudden and then wen i would step on it a lil it would loos manifold pressure
