Question about 2000 GMC New Sierra 1500
Did you make she that the battery has the right cold cranking amps, or the alternator? some times on an alternator the selfegnighter might have gone bad. Also sounds like there might be a wiring or fuel injection problem. Is there a check engine light on? Start simple, put some sea foam in the gas tank (you can get sea foam at auto zone for 10.00) that might cure the rough idle.
