    Default Hesitation/surge

    OK. I finally got the 87 suburban running. But it still has the same issues it did before it broke down. Sometimes not all the time, but lets say 90% of the time it has slight hesitation right off of idle. It will also surge when it gets into the r's. Could this have any thing to do with the emissions part of the motor? The engine light is not on, seeing how I have replaeced every sensor on this thing. I have also replaced the plugs and wires. And the injectors. It sounds like a plug or wire problem to me, but i'm not positive. Any help would be appreciated.

    Have you replaced your fuel filter? How is your fuel pressure? I see you replaced the injectors so try troubleshooting the whole fuel delivery system. Hope this helps!
