Small idle revving

Hello,

Just joined the Crown Vic family with my 2003 P.I.

After driving the car for a few days I'm falling more and more in love with the car, especially the sound of the 4.6 through the straight pipes, I've noticed a few quarks of the car and thought I'd see if any of you out there that may have some tips or insight to them.

First issue being where upon start up of the car, the O/D light flashes for awhile. After driving a minuet or two it stops and I can control the over drive function again.

Second, every once in a while while the engine will want to rev up maybe 200-500 rpm. This is a guess as I have no tach, but the 2 previous vehicles I've driven were stick.

Third and last (not sure if this ties into the second or not) .. I'm not 100% sure how to describe.
It's happened twice during hot and humid weather. After driving the car for about 10 or so miles the sound and feel of the engine change to a bit of a slight putting feel and sound. First time it happened I just gave a little to the accelerator and it went back to normal. Second time it didn't resolve the issue.


Thank you for reading and ANY help would be appreciated.

Three wires came loose near the fuse box during battery change. Soldered and crimped em' and she's running smoother then ever. Looks like this forum is useless for help. Good day

Sorry Adam. Im a newbie also and this forum is kinda quite. I just think we do not have many mechanics on here. I know with my other car I belong to a club where they will fight over who answers first then debate over the answer. Anyway that's what I'm thinking. I know I can't be much help as I am not mechanically inclined.
