I just read in the EFI book that a bad tach signal to the ECU can cause certain problems. My tach wire to the ECU is reading 8.4 volts during the test due, I think, to the resistor I've added to make my tach work. Has this caused anyone problems before? I'm going to try moving it so the ECU gets full voltage.
