'82 Coupe-CSV

[DBF]

Ti, thing is, the 12v is constant.  Once the car starts, the CSV continues
firing causing the mixture to be extremely rich.  The car wants to stall.
Right now, if I was to start the car and let it idle for a minute or so (CSV
unplugged), there would still be 12volts at the plug.  If I were to plug it
in, the car would stall.  I tried unplugging the TTS and it never made a
difference.  That is why I'm wondering if the relay is pooched, or did I do
something while the fuse panel was toyed with?  Beats me.  BTW, I forgot to
mention, there was a dash swap done a few years back by the PO.  It was a
border-line butcher job.  I suspect, after thinking about it a little
longer, the possibility of a sub-par swap of the dash may be causing the
problem as well.  If your deduction is correct about my car not having a
relay, how would I check the TTS?
