HYUNDAI SONATA CHECK ENGINE LIGHT PROBLEM

2003 Hyundai Sonata • 155,000 miles

Car idles about 2000 when started then jumps up and down - runs kinda loud and rough also - just started doing this - check engine light was on until I pinched the yellow hose on the egr valve, then went off - was told it could be the vacuum switch or egr solenoid?

Check for vacuum leaks and check the idle air control valve.
