I have an 88 chevy k5 4x4 5.7 blazer. I just changed the injectors and now when I turn the truck on it idols rough. I took it around the block and it feels like it's getting too much fuel or not enough fuel. When it's in neutral if I punch the gas pedal real quick it wants to kill. Thanks for your time.

 

A quick look at the plugs should tell you if it's rich or lean.
