i have a 1999 gmc sierra 4x4, it starts but runs rough, bad enough to where you cant move the vehicle, if you try to give it any gas, it stalls/dies. it starts back fine but only idles at around 3 to 4 hundred rpm, and in park it will also stall if you give it any gas. although if you just let it idle and dotn touch the gas pedal it will eventually die after about 20 or 30 seconds. i just changed the fuel filter and got no change in the problem.. ?? any ideas?? thanks for any help
