Driving home doing about 70 on the freeway, my tach on the guage and DIC dropped to 0, and stayed there for a about a minute, then engaged again. About 10 minutes later, it happened again, this time from stop light to stop light traffic. Again, about 1-2 minutes later, it started working again.
Anyone know what's going on. I changed the plug wires about a week ago (Magnecore wires). Other than that, I have a nitrous system with a MSD window switch hooked to the white wire (tach wire), but it's been hooked up for a few years now.
Not to state the obvious - sounds like a loose connection, just double check your tach wire, make sure you did not stetch out the connection or otherwise pull it loose
