Lean codes driving me nuts! Help!
Hello all, I'm on here asking for all your cumulative assistance to help me solve these codes that ive been getting.
-Lean codes P0171 & P0174
- P0131 Misfire due to low fuel
and P0505 ICV failure
The codes are intermittent and randomly trigger the SES light and vice-versa. The car runs perfectly and idles well the only thing noticeable is the decrease in MPG.
So far I've:
-Changed both intake boots
-New VCG not so long ago
-New fuel pump and fuel filter (2 days ago) along with new fuel hose and vac hose
-New Disa (old one was torn up)
and i've Cleaned the ICV
I also checked the oil drain hose from the CCV and it was fine/not broken
any help would be greatly appreciated! TYIA!
