HYUNDAI XG350 SENSOR PROBLEM

2003 Hyundai XG350 • 190,804 miles

I have an 03 Hyundai xg350 that repeatedly pops codes p1110 & p1171. I've replaced the pedal position sensor & maf sensor. Still wants to run high rpm. Any suggestions what to do next are greatly appreciated. Joe

Check throttle cable for binding ie. Holding throttle open. Also check throttle plate for carbon build clean if needed. Ckeck for air leaks after throttle plate
