Fixed Cold Start Now bad idle

[amalventano1@home.com (Allyn)]

    Since your idle problem appeared only after messing with ground, i think
you may have removed the ground for the harness. That thing needs a solid
(read - battery) ground for the engine to idle smoothly. You may want to put
that stock ground back on there along with the extra one. Its been snowing
the past 2 days here in charleston, and the rieger wouldnt start this
morning until i hooked the battery charger up using block for ground. I took
that as a hint to add another wire, which i did over lunch. I havent tried
starting it 'really cold' yet, but we'll see what happens tomorrow morning.
As for the idle, I had a bad ground before and adding a wire didnt change
idle a bit (some of you may remember im really sensitive to idle speed, as
it was part of my past overheating problem).
Hope this info helps.
