I have a 2001 Kia Sportage and its been a good car. Recently I was driving and had a sudden loss of rpms. I had to reshift into gear or gun the engine and it would come back up. It also started idling very roughly. I put in a fuel injector cleaner and that seemed to help, but it was still giving us sluggish issues in 1st and second and idling very roughly bearly holding 1 rpms. So we replaced the fuel filter, but it still idles roughly and it is slow to start in 1st and 2nd gear. Any clues. Spark Plugs, next?
