Hello peeps,

Got my spark plugs replaced due to System too Lean error. Seems to have fix it but came back. Any ideas on what may be causing the issue?

I also noticed too much MPG gain since spark plugs ( yes I said too much, it doesn't seem normal to me that something so simple can improve milage by so much) I used to get 250 miles tops on mixed driving per tank. Now I'm at 107 miles and barely used a quarter of the tank and trip computer says i got 250 miles left.

I still drive the same , to the same places so no changes there.

I also got these ones...



Everything seems to be pointing to the evap system but what about the system too lean error?

Change your n80, you should be good to go unless a bigger issue.
