Help with OBD diagnostics

Am I interpreting this right? It is a 4 cyl so there is no bank 2
  • Long Term Fuel Trim Bank One: 17.94 % ...... It is adding much more fuel than it thinks it should
  • System Too Lean .... Intake air leak?
  • Absolute Throttle Position: 19 % Engine RPM: 753 r/min ........ HUH?
