Plug in my MODIS on this 1990 Cadillac Seville, try to go to Data stream, and I can get a readout for maybe 5 seconds before the digital dash shuts off, the ECM cuts the data stream, and the whole thing re-sets. It just keeps doing that... blinking on and off.
If I un-hook the MO it's fine... any ideas?
BTW,what I'm trying to chase down on this car is the fact that even with the timing set correctly, it still acts like the timing is too far advanced on startup and run (chugging/fighting on starter engagement and pinging once running.)
