Re: Loose battery connection or tuneup needed?

I noticed yesterday that there is no surge when I start it up initially, it
runs smoothly. It's only after it's warmed up that this happens.

A bad connection on the battery is more likely to cause difficult
starting.

Also, when the engine is running, the alternator is supplying all the
voltage the vehicle needs.

What about at night, do the lights sometimes dim slightly?

A possibility is a faulty alternator or maybe an intermittent fault in the
charging circuit. That would explain the gauge fluctuating, but I don't
know how that would cause surging.

I have a '93 Explorer Sport and just recently noticed that the engine
surges when it is in either drive or reverse and the needle on the battery
gauge will dip for just a short bit (less than a second). Curiosity got
the better of me tonight on the way home and, when I stopped to get some
gas, I popped the hood and touched around the battery connections on the
posts and moved the battery ever so slightly. On the way home (not very
far) I didn't notice the battery needle jump, but there is still the
slight surge in RPMs which most likely are normal.

I have had the Explorer for a little over a year now, and don't have any
idea when it may have had its last tuneup. Any thoughts? Thanks, as
always, in advance for your input.
