Hi Lead Head, since you replied to my last post I will see if you can shed some light on my 86 B2 problem. She starts fine all the time. After warmed up and driving for about 5 miles or so I stop at a red light and the idle goes really low almost to barely running. I can hold the pedal to the floor for about 5 to 10 seconds before she picks up the rev. While holding pedal down she is sputtering. If this happens while driving B2 would sputter and buck then I would floor gas pedal for same amount of time roughly then she would take off. Bad scenario if under a red light or something. Things checked/replaced: fuel pressure at 32-36 psi, O2, MAP, EGR, PCV, ECM, TPS, radiator replace and flush out, plugs wires and coil, distributor cap and rotor replaced. Throttle body cleaned (sea foam spray), bad vacuum lines replaced and checked for leaks at this time. If anyone can shed some light on this issue feel free to pass on any knowledge you may have. Thanks
