2003 kia rio I changed the fuel filter the car idols but when i step on gas pedal it sputters then dies do i need to change the pump?
Had similar problem, 2003 rio 1.6l idle fine and die when trying to accelerate or lurch and die ran fine in reverse change timing belt,wires plugs, had codes for multi cyl misfire and low injector voltage, still same lurch and die. try wiggle test on sensor plugs and main engine harness between battery and engine . i did this and found car smoothed out,tried wiggle again and car died,took harness apart where i wiggled it and found broken wire to crank sensor.good now
I have a 2004 Kia Rio and it does the same thing. I changed the fuel filter and timing belt and it still does it. Did you solve your problem?
Is the fuel filter a in tank one if so check to see if the o ring for the outlet line isnt still in the old filter
Have the fuel pump pressure checked to make sure that is the problem.

I had a similar problem, exactly the same... it was a dirty mass air flow sensor... dirt on the little resistor in the sensor caused the engine to think there was no air coming into the engine when you step on the gas, causing it to not inject any fuel, the engine won't rev up and just moans and sputters. CAREFULLY clean the MAF resistor, it probably has dirt or carbon on it. change the air filter... try it again. If not, try replaceing the MAF. You may or may not get a code on this.
