You said you changed the speed sensor... but what about the pickup-coil code, is it still there? If I'm not mistaken (please correct me if I'm wrong), pickup codes have to do with the PIP signal from your distributor (PIP stands for Profile Ignition Pickup), which means the hall effect sensor in your distributor (which is also your CMP) is sending faulty ignition/timing information to your computer. I'm not 100% exactly how that system works, but I know that you NEED that signal for it to run properly. Could also be a TFI module intermittently failing. I'd definitely take a look at that Distributor and the module attached to it.
