Stuttering in idele and acceleration

Has the fuel tank been low lately? How cold where you are? Add 2 bottles of fuel "Heat" to the gas tank, and be sure to fill up...and keep fuel level above 1/4. Hope this helps.

Civic EX 1997 D16Y8 fuel economy problem (waisting fuel)

The most typical thing to go out that will waste fuel is O2 sensors. They can be marginal where they will not throw a code but will not be efficent. You can test the operation with a good scan tool or just buy two new ones. Also buy a can of "Seafoam" and dump it in your tank next fill up

Use too much gas

Check that your Exhaust Gas Recycling Valve (EGR) is not stuck or plugged. A percentage of exhaust gas is recycled through your intake manifold. If the 10 percent,15 percent, 20 percent, etc.exhaust gas is not sent through the intake manifold it has to be replaced with fuel /air mixture. Using more fuel/air instead of spent gas lowers your fuel economy. Other things, try using fuel system cleaner in your gas, make sure your air cleaner is not dirty or plugged, new plugs can make for smooth running, bad distributor cap, bad wires , etc.

I bought a 2000 civic with 67000 miles on it and it ran ok and was getting 38mpg notknowing about the car i bought plugs wires and distributor cap ingition rotor it had autolite plugs in it so someone had...

the only thought that comes to mind is to re-check your spark plug gap, the reason is that if the gap is slightly larger, plug efficiency will drop, thus fuel economy and power, please confirm that some platinum plugs the gap is not adjustable, (.044 thousands) good luck!
