2002 Hyundai Santa Fe

Engine Mechanical problem
2002 Hyundai Santa Fe 4 cyl Two Wheel Drive Automatic

recently purchased a 2002 santa fe with only 67,000 miles. Am having a high rpm problem when vehicle is in park. It will sit and idle at 2200 rpm. Found a post on this site which steered me to replace the temp sensor. However, it did not cure the problem. Is there a break in period when replacing electrical parts?
