How to install new fuel filter and clean MAF sensor? o2 sensor replacement?

[onosqv]

Hi, I tried the search function, but I wasn't able to find anything definitive, and maybe because it's really late and I'm going delerious.

Anyone have a link/pic of installing a new fuel filter? how often am i suppose to change this thingy, lately my car has started rough idling and I think fuel filter change is overdue. I'll be changing sparks/spark plugs etc in a few weeks after I finish up some other stuff or the car.

How about cleaning the MAF sensor; what kind of thing should i use to clean it (water, alcohol, etc)? I think mine may be dirty.

Anyone have a link/pic of replacing the o2 sensor?

fuel filter is on your passenger side of the engine bay you can't miss it, it looks like a small metal cylinder. You can change it through #1. pull fuse for fuel pump and start car. run it till it dies. then uncap your fuel cap. Go back to your fuel filter and undo the screws on the fuel line clamps and twist the fuel line right at the filter. It'll take a bit of work to get off if it's your first time. Toss in new filter and fuse and put the key into position just before start to let the fuel run through the filter.

MAF sensor use brake or carb cleaner, not directly on it, but let the fluid run over it but not at high pressure since it's pretty fragile.

o2 sensor is on the exhaust manifold and has one green wire running from it. you'll need a 22mm deep socket with one side cut out (for the wire) to get the bugger out. that's bascially what the tool looks like for the o2 sensor. they do make them premade like that so don't think you've gotta hack up one of your sockets.

You got ripped on that tool. I only paid 11 bucks for the tool at autozone.
