I'm not sure if this is in the right section, and I apologize if its not. I have a 92 Chevy Blazer with the 1500 tahoe package. The issue i'm having is that when you give it more then just a little bit of throttle it will hesitate like it wants to die and then start moving after a second or so of hesitation. It also seems really sluggish. Where would be the first place to start? All I have done was put in new plugs and there was no change. Thanks
