200 miles to the tank?! (city)

That's unheard of.....

WTF - I've already replaced my fuel filter, cleaned my TB, no exhaust leaks...

Could teh pcv valve be causing this? I cant afford only 200 miles for the WHOLE tank..

knock sensor caused me to drop 5 mpg in th winter time...went from 19 to about 14, sometimes lower. it prompted me to check for codes when i saw this happen for 2 tank fulls, and after i replaced it was back to 19 mpg

I can get 450 to a full tank of gas if I am traveling.

I have had some issues with my MPG dropping, idle not holding,sputtering. and took me a while to get it right but here is a list of what I did...

Spark pluggs
PCV Valve!!
Clean the intake with seafoam thru the brake line booster.
Clean the TB
Clean the IACV
Fuel Filter
Fuel Injector cleaner
Knock Sensor
