Yes it's normal, I don't know why it's like that but my truck does the same thing, my guess is if have to let the clutch out in an emergency it shouldn't stall right away but rather chug, which could save you from being hit.
Almost every fuel injected car has a high-idle or rpm offset triggered by a VSS threshold. This is completely normal. Offsets are usually in the 300 rpm range with thresholds around 5 to 7 mph.

Regardless of clutch position, under the VSS threshold you should only see base idle (+/- accessory rpm offsets). If you're rolling with the car out of gear faster than 5 - 7 mph, you should see base idle + the high-idle rpm offset.

Why?

So if you find yourself coasting out of gear at 30 mph (for example), accessories still work, power steering has pressure, alternator still charges, etc.

Short answer: your car is perfectly normal.

I think you're stating that after taking the foot off the gas, engine does not immediately return to normal idle speed....like 750rpm.

I cannot seem to find the proper answer online, yet having previously been an auto tech and a person who did smog checks in Calif., I'd say this:

If an engine returns from high rpm to idle speed too quickly, that will cause temporary high emissions output...unburned hydrocarbons mostly. A delay in that return to idle speed helps produce fewer emissions. These days, the auto engines computers are programmed to accomplish this automatically.

As for a/c: Engaging the clutch of an a/c compressor, starting action of that compressor, puts a load on the engine. Computer knows to raise the idle speed temporarily so that engine will not stall.

I coast with my clutch disengaged sometimes because of city driving.
Drivers can be erratic so it's not far fetch to have to go
Sixth gear>clutch in(coast as moron in front of me is lost) fifth>fourth>third(moron turns) >clutch out>accelerate
During that my RPMS are always at 1000.

OP if your clutch wasn't disengaged you would feel it in your foot. And probably hear it depending on how much is still engaged.

In the fr-s I switch gears at 3.5 when cruising and when racing around about 5k rpms. Feel like the power band is around 4-5 depending on speed.

This is confusing to me. Why would you go down through the gears as though downshifting but without letting the clutch out?

I would either actually downshift or put it in neutral and coast until time to go again. (FWIW, I'm no expert but I have driven sticks for almost 30 years, without damaging or prematurely wearing out any of them.)

I do the same thing. Just so you're ready and in the right gear when it's go time.

Edit: But yeah a real downshift would be ideal I just can't heel toe yet. *blush awkwardly*

Exactly. I would not want to coast in neutral at any time as I have had to avoid things in the past and wanted the power then not in 2 more seconds.

I don't find it a problem to go from coasting in neutral to in the correct gear under power in very short order.

If you think about it, the only difference to what is described above is I'd be letting the clutch out and not doing these "phantom" shifts that mostly result in nothing happening. You still have to do the same thing I'd do and pick which gear to be in based on your speed. At most you save the time to clutch in and pick a gear. Just seems like extra motion for nothing most of the time.

I guess a lot of my habits come from the training I had as an army truck driver. The truck was always in some gear while moving. You ever got caught "free wheeling" in neutral you could expect a stern lecture at best and extra duties at worst. Same with traveling with the clutch in, anything more then a few feet when coming to a stop was a no no.
The theory being that if something happened and you had to maneuver the transmission was already in gear so it was just gas and go, not shift gas and go. That split second shifting from neutral could make the difference in a bad situation. I know that doing this saved my bacon more than once over the years.
Not for a second saying my way is right or wrong, it is just what I was trained for and is habit now. I doubt if I could force myself to actually coast in neutral even if I wanted too after driving the way I have for 40 years.

Damn. OP, your car is fucked. I'd go to the dealer and demand a new car.

I think we scared him away!!!!!
Would pay money to see service writer's face when he walked in and said "my car only drops to 1rpm when I push in the clutch"
Good luck getting them to duplicate that statement for warranty work!
