Acting up and won't idle smooth?

--------------------------------------------------------------------------------

I think I solved this already and wanted to share. My 86 Charger had been acting up and idling high. It had a code for the speed distance sensor and I had changed the TPS. Yesterday on the way out of work, it just up and quit. I coasted into a handy lot and just stared under the hood a while looking at grounds and things. There was no electricity at all, no lights, gauges, nothing. Found a plug in the heavy battery wire going into the wiring harness had come apart. Plugged it back together and all was well again. When I got home I cleaned it up and put a cable tie around it to hold from coming apart again. Found that if the positive terminal is turned a 45 degrees on the battery, there's less strain on the plug, the wires are a little stretched for the intercooler installation and such.

Best part of all this is the car runs better than it has in months. No high idle, no holding revs up between gears, smoother idle and in general real happy going down the road. I'm thinking this plug was working loose and driving me nuts by providing weak or varying voltage to everything.
