'02 Taurus hesitating to start

So this '02 Taurus with only 87k miles on her starts right up every time multiple times a day except for twice in the last 3 weeks. The first time was 3 weeks ago and the second was today. It happened the same both times. Turn the key and stop to let the pump prime, then when I turn to the start position the engine turns real slow and sort of in fits. Usually when a battery is low the engine turns slow but in rhythm. During my 2 starts the engine barely seemed to turn and the crankshaft rpm seemed to vary. On both starting events I let off the key and tried to start 2-3 times with rests in between. But then eventually on the 4th try it starts right up just as quickly as a normal start.

I have No clue as to what might be causing this. Only thing I know to do is, next time it does this to put a voltage meter on the battery to see if it's weak. Actually though, because both events the engine ended up starting up like normal that would indicate something other than the batt. Electrically this car is a little odd though. The interior light never comes on when the doors are opened, for years, and then last week it comes on twice when one of the rear doors is opened.

Clean and tighten your electrical connections.

That was my other thought was to clean the batt terminals. What other connections should I clean. Only other one I can think of is the starter terminals.

Most often people forget that battery cables have two ends. They will happily clean and tighten the terminals at the battery but will neglect the positive cable connection at the starter and the negative cable connection at the chassis or engine block. If the car has a separate ground strap from the engine to the chassis, that needs to be attended to as well. While going over your connections, be sure to check the condition of the cables as well; you don't want cables that are corroded or have multiple broken wire strands, and if you're using bolt-on cable ends be aware they are much inferior to crimped terminals. If you continue to have a slow cranking issue after taking care of the power and ground circuits for the starter, have the starter bench checked and the battery load tested.
