welp...165,700k miles and finally my first fault code. Check engine soon light came on this morning on drive to work. i have noticed this week that when i first started the car it ran but then seemed to very briefly change its normal hum and stumble very very briefly then go back to humming as normal.
throw the reader on it and it comes up with
P0174 - Fuel Trim, Bank2 System too Lean
Any ideas what exactly this code is referring to? what can i check?
