Well here is what I found. I disconnected the idle controll valve and then the idle settled down so Its not a vacum leak. The rotor cap, wires, plugs, coil are all less then 5 months old. Where is the TFI located is that the ignition module. I also tried pulling the ignition timing conector( the little plug you pull to set the timing) so the timing would not change. And it got worst, the bucking that is. Now timing I had just recently moved my timing back when I began putting 87 in it. Question first what controls the Idle control valve and second how can I make sure my coil is well grounded to the block.
Thanks
