I own a 1997 Hyundai Tiburon FX 2.0. relatively new motor (between 200-400 miles on it). I bought it from a private owner about a month ago. I have been having problems with it lately. The Idle is at about 1300-1800 rpms. When I start driving it it jerks a little, but I put the pedal to the floor it starts jerking even harder. I've replaced the fuel filter twice, checked plugs and wires. Cleaned out the injectors. I don't know what else to do now.
If any of you could be of help I would greatly appreciate it.
