I can feel a miss in the gas pedal. It is constant and I feel it more the higher RPM's I run.I have a vac leak some where I can hear at idle and I also have a broken weld in my collector in my headers. Could those two issues make my car miss? Just testing the water for ideas to fix the problem. The exhast gets fixed tomorrow and I have a LS6 intake manifold going on the car tomorrow night. Let me know what you guys think.
