Question wierd idle and tach

about 2 months ago I took the car out and it started to run real rough and the tach went to 6000 rpm when the engine was barely above idle. I brought it home and when going over it at home I found that my battery ground was loose, tightened and no problems since then.
Until today , as I was warming the car it did the same rough running thing and the tach went to 5500-6000. I shut it off and checked the battery and it was all tight. I waited about 15 min. and re-started the car and it ran perfect, took it for about a 25 mile spin shut it off twice, no problems with the way it started and ran.
Any ideas why its doing this? I'm thinking maybe one of the ground straps, how many straps are there and where are they ? any other ideas? Its an 87 930
