I get bad mileage like that as well...I think it might be either be one of the O2 sensors or the MAF. I too had a CEL indicating "too lean". I bet it is the MAF crapping out or the fuel filter really clogged.

Guys, correct me if I'm wrong but the DEALER said the fuel filter in our cars NEVER have to be changed???!!! Not sure if that sounds right? Has anyone changed ther fuel filter yet?

Yeahhh!!!!!1

I'm not sure if the dealer told me..but I DEFINITELY heard that.

And when I went to RS strauss for a replacement filter...It didn't show in the book = Dealer only item...

So I think your hitting the bulls eye with that pooint..

and the other point..

that most likely we are having a MAF and/or O2 problem!

:-(

Sucks...


Let me know if the code comes up again...you can swing by and run it through my OBD

Ahhh!!

Let's not talk about Long Island!!!

I went with these two girls yesterday to Montauk!!
THAT IS THE EDGE OF LI!!!

nearly 150miles away..

Was there for 5minutes than SPED my *** off into the CITY for class..

EASTTTT TO WESTTTTTTT

It was a crazyyy drive..fun -- but exhausting!

Exit 60 is far!
I'd be down for a mini meet around Exit 30-40 (Ikea lot)

Back to mileage...I've been getting incredible highway mileage...So I'm considering the possibility of just simply having too much stop and go traffic like Cliff suggested...


I used some techron again, and have been primarily been doing highway driving to really work that cleaner into the injector...

As I mentioned earlier..abt the Check engine light..I am going to wait abt 1 or 2 more fillings and if there is still a problem I hope I get a check engine light on for the O2s or MAF.


If not I'm definitely going with what Shocker reccomended with the Fuel Injection Cleaning and the Decarb.


So lets get THIS MINI MEET GOING!!!!!

1. Tantra
2. Excluesive
3. Rock-A-Lex
4. TommyJaix
5. we should make a seperate post for this, lol

Yea speaking of bad mileage I've been getting crap local mileage going to and from class, a total commute of about 20 noncontinuous miles a day taking up probly about 4 trips and my mileage dips to about 17mpg whereas on the highway my mileage is pretty solid at about 20-23mpg

actually it might be lower than 17mpg locally, 17.6mpg was my average with 90% local and 10% highway driving. during the summer when it was more like 60% highway and 40% local i was getting a good average of 21-22mpg.

Speaking of mini meet, y dont we all drive go shopping together on black friday lmao
