Went in for an intermittent engine hesitation 2010 Hyundai Elantra. I was over due for tune up. Diagnostic and road test found the problem quickly. Found OIL on Spark Plugs. Needed a cylinder head gasket. Actually did the entire engine work while I waited and got me finished in time for my Noon Shift start time. I was Stunned at the reasonable $$ Cost for this work. Car runs GREAT
