CHEVY ROUGH IDLE

2004 Chevrolet Colorado

Engine Performance problem
2004 Chevy Colorado Two Wheel Drive Automatic 104000 miles

when I crank my truck up and put it in reverse it acts like I am feathering the gas but it idles that way how can I fix that?

Try cleaning out the idle air control valve and test the throttle position sensor.
