Code 16 indiates the EGR valve needs to be replaced. It's located on the outside (passenger side) of the Lower Intake Manifold. Here's a picture of the LIM. The EGR connects right in the middle (the area where you see two holes side-by-side, and a couple of studs). Unfortunately, I don't have a very good picture of the EGR itself.

EGR Switch Bypass: the EGR switch is the sensor that causes a check engine light ( code 16 ) when it doesn't detect the EGR valve opening and closing. This sensor tends to fail from heat, and give a false alarm even when the EGR valve is working properly.

Ok guys thanks for the help ill try it and let you know. In the mean time in 96' there was a recall on a brake vaccum line or something this never was replaced and i was thinking about gettingit fixed but im iffy about going to the dealership with it. Any suggestions?
Make sure your car hasn't had the recall done. I had the brake recall done on my car after I got it, but I really think it had already been done.
Anyhow, it's actually VERY easy for Mazda to do the brake line recall - both lines are accessible without removing anything - just remove 2 hose clamps, remove the line, and install the new one. Takes 5 minutes, tops, and a pair of pliers.
I shudder to think of Mazda techs doing the fuel line recall back in the day!
