Engine Mechanical problem
2003 Hyundai XG350 6 cyl Front Wheel Drive Automatic 110000 miles

My engine light came on and I took it to see what was wrong. They said it was a misfire code and that it needed a tune up. The cost would be $592. I thought that was a little excessive. The repair shop said that in my car the top of the motor had to be removed in order to reach the spark plugs.
