You may either have a partially clogged Catalytic converter or you may have a MAF Sensor (mass airflow sensor) going bad. When it seems to loose power, does it want to backfire through the intake? If it does, most likely the MAF Sensor is going bad. If the car seems to drive just fine at first then starts loosing power gradually while you're driving, the Catalytic converter is most likely partially clogged.

It sounds like you lost oil pressure. This could be from lack of oil or from the pump not working. There's probably a safety switch that kills power to the motor when this happens.

How do I improve my fuel economy in my 1997 Hyundai Sonata GLS?


Here are some tips on how to improve your fuel economy:
- Going fast is so tempting. Not only do we do it to keep up with the flow of traffic, but if we can save even five minutes, it seems worth it. But if you're on the highway, driving 60 miles per hour instead of 70 mph will save you 2-4 miles per gallon over the duration of your trip.
- Take it easy on the throttle. Don't accelerate quickly or stomp on the brakes. Coast to a stop. You'll save on fuel as well as wear and tear on your brakes, which will save you even more money.
- Shut down. If you're waiting somewhere for a while, like at a train crossing for instance, turn off your engine. Even if it's just for a minute, it can make a difference in your fuel economy, especially if you drive in the city a lot.
- Don't warm up your vehicle for more than 30 seconds. This is a tough one, especially for us here at Consumer Guide®, where Chicago's frigid winters are a way of life. Thanks to technology, however, most modern fuel-injected cars only really need 30 seconds to warm, and hot air can start blasting into the cabin very shortly thereafter.
- Windows up. Again, this is tough, especially on pleasant days. But having the windows down creates aerodynamic drag that causes an engine to work harder. On the highway, this can decrease fuel economy by up to 10 percent.
- Check your tire pressure. Making sure your vehicle's tires are set to the recommended pressure can increase fuel economy by as much as 3.3 percent.
- Breathe easy. Next time you get your oil changed, have the air filter checked as well. Replacing a dirty air filter with a clean one can save up to 10 percent on fuel costs.
- Make sure your vehicle is in top running order. Read your owner's manual and follow the manufacturer's recommended maintenance schedule. If it's time for a tune up, do it and you can realize up to a 4.1 percent increase in fuel economy.
- Buy the right gas. Your owner's manual will list the correct octane gasoline you should use for your vehicle. Purchase whatever is recommended and no more. Premium-grade fuel is more costly and won't improve economy in vehicles designed to run on regular.
- Lighten up. The less weight in your vehicle, the better your fuel economy. Clean out that trunk!
- Grease up. Using the manufacturer's specified motor oil, and changing it per factory recommendations, can improve fuel economy as well.
- Combine trips. Don't run out two or three times a day. Hit all the stores you need to visit at once, and if possible, go to shopping malls where you can park and walk to several stores at the same time.
- Cool down. Gas up on cool mornings. Fuel is denser when cold. Gas pumps measure by volume, so if you pump when it's cold, you get more gas for your buck.

At acceleration has fluttering effect and no power


as i read your description i assume that the fuel filter terminals are not thightend correctly any more, or that the new filter as not perfect sealed. see for remnants of fuel near the filter. if it is fuel wet there, then a leakage is the reason.

Other reasons are possible.

Lack of power


There seems to be some kind of fuel (gas) starvation, check the fuel filter, check to the fuel pump could be weak.
Check the spark plugs, the condition of them will give yousome direction to go about it all.
If its whitish =lean means lack of fuel (gas) and by your explanation it should be whitish.
If its a carburator model thn it may need cleaning.
Not bad to check the distributor too.

Hope this helps!

Have u checked to make sure that the fuel filter isn't plugged, and it could be possible that the fuel pump is bad -being cracked or haveing a bad seal in it allowing fuel to leak back in the gas tank, as soon as your fuel pump warms up the leak would expand dropping your power
