Hi Charles,

Is that +20% or -20% for your LTFT?

NYC stop and go driving will kill your mpg easy.

if thats a + ltft you likely got a vac leak somewhere.

if its a neg - number you could have a stuck open injector, check both banks, see if ones richer then the other, then you know its an injector if one side is higher neg #.
