The gas filter should be changed at 30,000 miles, the AC pulls about 5-10 horsepower from the engine when on, you will feel this, the Kia has a small engine, if you are talking about a more serious drag then you may have the system overcharged or the compressor is starting to fail.

Fuel filters should always be changed when you due an oil change. bad fuel filters is the number one reason of fuel pump failuresand bad engine performance. the reason for loss of horsepower with the a/c on is because your engine has to work harder and it uses more fuel. this should only be a slight loss. if it's a dramatic loss then it's a different problem. in order for me to help you more can you be more specific in detail.

Wont stay running for more than 5 seconds.

This could be a lot of things. IT could be bad gas, it could be the fuel pump, it could be the injectors or the crank sensor. It is too hard to diagnose without a scanner. If you can get a scanner from someplace like autozone and see what codes are stored, it would be beneficial to us.

If it jerks going up the hill I would sugest plugs, leads, coil etc... If not when was your fuel filter last changed? Also check for split intake tube or loose intake clamps.

Why my 2002 kia rio stalles out everytime i step on the acceleration and keeps getting worse i changed spark pluggs and air filter and fuel filter please help me oh and everytime i go up hills i loss speed...

you need to check your fuel pressure at the rail with a gauge. But to me it sounds like the spark plug boots . If they crack or split it will cause symptoms just like yours, mostly shaking while under load. Since you already changed the plugs change the boots or wires too.

I changed the fuel pump in my 2002 kia rio but the gas gage still dont work

Gas gauge has nothing to do with fuel pump. possible causes:

1. Low fuel in tank, get some more fuel
2. Rat chewed the fuel gauge wire or its socket is loose
3. gauge itself is faulty

My Kia Rio stalles while in drive and reverse. Is the fuel filter bad or isit the air mass sensor?

If it runs, and you can throttle it up in park, it's not a fuel filter. You need to know what it looses when it dies, fuel or spark.

check the fuel line hose near the fuel regulator for wear as they tend to leak or corrode causing a gas smell inside the car. My 2000 Kia Sportage just had the same problem with the gas smell inside the car.
