2012 Kia Sportage Q&A

2012 Kia Sportage Question: I'm having hesitated accel. & slugishnes engine run, what's the possible cause?

I have a 2012 Sportage EX 2.4L w/18,000 miles, and I replaced the air filter some 10,000 miles ago. It went running fine, but from some time its been running irregular and slugish specially if I drive it with a light pedal (low rpms); once I push down the pedal, it start accelerating with dificult up until it smoothes and it goes fine. I am getting tired of driving high rpms to avoid the hesitation. Is it something I can do? -
