Try running some "Sea Foam" motor cleaner through it, it come sin a white and red can, about 5 bucks. I just through a can of it in my tank to try and clean my injectors out. I havent read one bad thing or heard one bad thing about and I researche dit for like 2 hours. i go tmine at Auto Zone. Try it out and if you follow the directions then it will clean every bit of anything thats bad out of your engine. Heres a detailed intruction link.

IF YOU'RE RUNNING A VORTEC TRY CLEANING THE IAC OUT WITH CARB AND CHOKE CLEANER.IT MAY BE STICKING OPEN GIVING THE ENGINE TOO MUCH AIR AT IDLE
