Car was sputtering bad. Had it floored and it would barely go. I had an aftermarket Bosch idle motor installed previously. So I swapped back in the factory idle motor and it was still doing it. I had the factory ecu installed, but Dave Mckeen's updated version on hand. I jumped the ecu diode, backed out the throttle screw and installed Dave's ecu. I also set the curb idle using the on-board led on Dave's ecu. When I went to set the fuel mixture the dwell needle wouldn't swing at all. Frequency valve isn't buzzing either. Car starts and the dash rpm needle continually hunts. The rpm will drop so low that it stalls out while hunting. Attached is a photo of where the dwell meter sits.
