I don't exactly remember who posted message about playing with a hex screw on Air Flow meter - That's exactly what i am doing now and here comes my first question and pictures
If you look at the pictures which way do you have to turn this screw (i guess it needs to be tightened)???


My second question is.... I don't have and actually don't know how to check with a voltmeter if my Air Flow meter is working at all - what are the symptoms of NON working Air Flom Meter???
This one goes to Bill R. : Bill you posted a picture of your broken cat - how did you find out it was bad????
My car is running really rich ( i think it is somehow connected to AFM - i am probably wrong with this assumption)
and i know that running too rich will damage Catalytic in some time... I am trying to fight my low MPG (11-12 MPG mostly city driving) and everything else is working properly (tuned up, but i have doubts in 8 mm ignition wires
from Bavarian).What else could contribute to low MPG?
I know that 535 isn't exactly a Civic and i have 18 inch wheels and it is auto - many people told me that it's a good consumption but 10 dollars for gas per day is kind of makes dents in my wallet
Another possibility is my fuel pump - i ran the car out of gas many times (part of MPG calculation project) and as Bill R posted pump that sucks air instead of fuel will go "south" - So can a BAD fuel pump contribute to a bad MPG?
So if anyone has ideas about anything that i've posted i'd appreciate an effort to help me in my quest.
Sorry for a really long post
Have a safe drive
