Changing the fuel filter and a MAF
So i just got my first car (used but good) a few months ago and recently came across the 'Schedule Maintenance guide.' It's a very cool book that keeps track of stuff. So I figured I'll just go ahead and go what is required for the current millage I am at.
I have a 2002 Ford Escort Zx2 SOHC single engine 4Cylinder.
I'm VERY new to cars and don't know anything about them ...except for the radio (I'm pro at that) and some of the common internals (AC lights etc).
So far according to the book I was able to do MOST the things listed myself like changing the air filter, spark plugs, and even the oil change with a new filter.
The only thing I have trouble now is changing the fuel filter and checking the Mass Air Flow (MAF).
I kinda self taught myself through internet and owner's manual on how to change things but for the fuel filter and MAF I kinda reached a dead end.
My question is, for changing a fuel filter on my particular car do I NEED to riser for my car? Or is it something I can do if I just pop the hood up.
And for the MAF, I recently bought a scanner (because my engine light was on) and when I scanned it I got a P0171 code which equals a System Too Lean (Bank 1). Now I didn't know what that meant so I looked it up online and it said that it means the MAF sensor is dirty or faulty OR I could have a vacuum leak downsteam of the MAF sensor.
Now I think I DO have a leak somewhere, but I just don't know how to check for a leak and when I do find it how I can repair.
I tried the owner's manual but it doesn't exactly explain where my MAF is or where my vacuum is (unless its listed under a different name, I only checked for MAF and vacuum).
Does anyone know a website or instructions on how to find a leak (and if I need a riser for this or just prop open the hood)?
Thank you for time and Happy new year!
