So i did a search and no answers...
Im getting the code P0174 on my car and i tried cleaning the MAF and i still got it ... its only the one code for bank 1 and not for bank 2 so i was just wondering what else it could be..
also when im in 3rd and bring the RPM's up to about 5000 i can hear detonation ( or what i think it sopose to sound like )
code means System to lean on bank 1 ... pretty sure theres no leaks, and the O2 is not even a year old... and im pretty sure theres no exhaust leak... bad injector maybe?
 
well...

I guess i was worng the code is P0174 witch is BANK 2 and not bank 1
i looked at the o2 sensor and it was fine... would home made O2 extenders make ths code come up? if not then i have no idea why im getting this code
