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..

 

hehe, I usally get like... 300mi for city(sometimes usally 280ish)

You know what im about to ask you right, is your KS good? lol probably is..

Do you roll with the a/c on alot??

 

AC....no not really. Maybe for about 10 min out of the whole day

Now that I think of it, I AM thorwing a KS code....but it was just changed ****** 2 months ago...

 

Maybe the KS harness is bad??

might wanna see why it keeps coming up, prolly eating up your gas.

 

Wouldnt I be running very rich?

 

lean....... change plugs

 

I get 200 miles or so all city driving...

 

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

 

i also get around 220 city, with a bad 02 sensor.... gotaa love new York, cause i still dont think that a good o2 sensor is gonna make that big of a change.. even before my o2 sensor whent bad i was getting about 280,, and thats still nothing compared to other people here on the org.. gotta love New York City

 

Bijan, how hard do you drive??? do you push it to the limit?

 

Nah........it's just that it's ATL sh*tty traffic....stop go stop go stop go.......no AC on or nothin

 

maybe it's the flux capacitator?

 

Nah, I had that checked out last week....it's running .05psi so it's all good

 

i got 2 harnesses. try some seafoam to help it out. won't solve the problem, but might help.

 

I got a code for my 02's and Knock Sensor... that might do it.
