    Yes, check gas filter to see when it was last changed, if problem started suddenly, not slowly, then you might have a fuel pump issue or fuel rail pressure sensor, and a clogged converter can cause symptoms, but it comes on slowly and is only noticed when under load of going up hill, does not happen quickly.

More than likely it is caused from not getting enough of fuel, Check fuel filter to see if its ok. God-Bless!

Does the auto cruise function during down hill after setting the speed?


Tambu: Yes, the cruise control should hold you at approximately the same speed you set it at even when you go downhill. Sometimes you will see it pick up a pick too much speed, but then it adjusts.

It bogs down when you go up a hill or when you give it full throtle


I had the same problem with mine, it did not pick up speed on the hills and max at 35mph on steep climbs. It ended up being a diaphram on the back of the carborator that does not come in the carb rebuild kit so you will have to find a carborator specialist in your area and see if they carry it. That diaphram controls the secondaries for the extra horse power needed for picking up speed and going up hills.

Lack of power when climbing hills and slow to pick up speed


It sounds like your vehicle needs a major tune-up. Try putting in some fuel injector cleaner gas additive and a new air intake filter.

2002 kia spectra has hard time picking up speed


I had the same problem. I changed my fuel filter too.Your catalytic converter is clogged. I could put the pedal to the floor board and couldnt hardly pick up any speed. I could hardly make up a hill on the highway. Take it to a kia dealership and they will, they should replace it for free, they did mine and I didnt have a warranty. I think there is a warranty on that specific part. That's what it is though.
