Chevrolet Repair: engine start, chevy venture, load testers

Question
I have a 2000 chevy venture. The engine statrts, but is beginning to sound sluggish when starting. The battery has tested ok. Is this possibly my starter?

Answer
Its starting to sound sluggish as in "it turns over slowly"?.  Have the battery load tested.  A low CCA will cause this problem.  You won't notice it wiht your lights and accessories as they draw very little in comparison to the starter. Check the CCA rating on the battery IE 600CCA and load test it.  Most load testers now will tell you the exact CCA and suggest when to replace it.  Colder ambient air temp the CCA is more important.
