spark plugs
fuel and air filters
transmission flush

and some other stuff but i don't know, try a search and don't spend money for labor, you can do all this yourself, its pretty simple, just buy the parts and do it yourself

You should definitely do these things yourself. An air filter, fuel filter, spark plugs... these are easy jobs to do at home. You won't have to pay someone a ton for labor charges. Many of the mechanics will do a halfass job too. If the air filter is a little bit dirty, he might just shake the dust out and put it back in. If the spark plugs look pretty good, he'll just put them right back in. If you do these things yourself, you can take the money you saved from the labor charges and put it toward some decent mods for your car instead. If you want something done right, you have to do it yourself.

clean your throttle body.

sorry if I'm asking a stupid question but....how do I clean out the throttle body? Is this a simple do it yourself job for a newbie?

It is not too difficult. All that is required is a few things:

can of throttle body cleaner
miscellaneous sockets
a rag or two
toothbrush and a little bit of time

Many people act like this is the miracle cure. It is not. I have not seen any proof that cleaning your throttle body improves gas mileage significantly.

If you are getting really poor gas mileage I would be inclined to pull your engine codes and/or test your O2 sensor and knock sensor to determine if they are working right.

There are several threads on throttle body cleaning. By doing a search, you will find some useful info on how to perform this simple maintenance.

Good Luck!

i found an article on a 3rd gen, but was looking for one on a 4th gen maxima. I'm on a very slow dialup now and it takes me forever to load up a page. Anybody have a quick link for me? Preferably like to have something with pics that I can follow to find stuff since I'm not very automatively inclinded.

Check the How To sections on these sites:

1. www.motorvate.ca
2. www.maximadriver.com
3. www.vqpower.com

My homepage on page 2 has some pics of the sparkplug cylinders, location of the PCV valve, and fuel filter.

Just do your research and give it a go. It's a great learning experience.

Good luck.

Check your ECU for a Knock Sensor code. A bad KS will kill your fuel mileage too.
