    Check the fuel filter on the frame. Do you know how many miles are on the fuel pump in your sub. If high mileage it would be a good idea to put a new GM pump in. Might check the egr because it will also cause a part throddle miss if going bad but it will normally turn on the check engine light. Hope this helps out some.

    Wow! I suddenly feel a LOT better about our '94 Sub having 132K miles on the clock. It's still got at least 250K left in it! /forums/images/graemlins/yikes.gif /forums/images/graemlins/thumb.gif /forums/images/graemlins/peace.gif /forums/images/graemlins/waytogo.gif /forums/images/graemlins/woot.gif
