about 7 this morning, while it was cool and damp(cool for here anyway) truck started up as usual, let it idle for seem like forever, probably about 15 min till it reached close to 180 degree, took off for a drive, went thru all four gears hard and steady, drove it about 15 min, it never stalled , die, or do nothing except run like a bat out of heck, so..............this may mean I have no lose wireing,,,and although I have ran it well without one of those carb-warm up deals, that may be my next option, in the morning, I will start it as usual , let it warm up for just a few min,not to operating temp, drive off and see if the gremlin is back,,,, although I thought it may have been electrical, I see no way that a fully warmed up truck or not would be effected by anything electrical...agree or not... thanks..Fred
