hello everyone. so when i started my 2007 G35 in the morning it was very rough and stalled, started just fine on second start. then in the afternoon when i finished my classes car started but was very rough almost stalling. after it got warm rpm stayed at 1100-1300ish rpm. and pulled SES light, checked it with cheap bluetooth obd and it was P0171 and P0174. checked everything i saw on forums and youtube, everything seems alright(no broken hoses or hissing sounds from engine bay). i hope i will find help here. thanks <3

 

looks like it's telling you it's lean on both banks. the easiest way to find a vac leak would be to smoke it. i suspect your intake tubes have small cracks in it.
