Questions:
How can you rev it up to 10000rpms?
Where do you race it?
Don't waste money 'till you get a proper diagnosis. Save money for the new engine first.

Well, according to the parts list I just created at Advance Auto Parts website, you are looking at $223.51 worth of parts for the ignition coils, spark plugs, and spark plug wires before you add in any coupon codes.

They are advertising code DCRP right on their website, which gives you 15% off, and drops the price to $189.98, and you get free shipping.

If you search the internet, you might be able to find a coupon code that brings the cost down even more. If you search the internet even harder, you might find other stores that sell the parts for less.

BC.

Here is a copy of the compression tests done by the dealership.

Well you might just double check both trailing coils and make sure that one of them isn't failing as this could result in a similar condition where the engine might otherwise still idle and start in spite of low compression

I don't know where you get your logic but redline the car once a day helps reduce carbon build-up but driving like an idiot "racing" on the streets redlining the **** out of it at every stop light is going to end up causing premature wear of your apex seals. Heat kills rotaries.

Faulty ignition parts actually affects compression and I can vouch for this.
I bought my 8 a few years ago with a "bad engine." I replaced all the plugs, wires, coils and had the engine tested. It not only passed but I managed to double the mileage out of it since I purchased it. I had the engine replaced eventually at 82,210 miles but it barely failed the test (1 before warranty expired).

Also, regarding the compression readings, where are the actual numbers? What RPM were they tested at?

At this point I would do a home compression test before spending more money you don't have on parts that "might" fix the problem.
<<< Hoe do I do a HOME Compression Test?

<<<< I have no clue, that green piece of paper I uplaoded from the dealership is what they gave me.

I don't see what the issue is. Dealer says its a **** engine, he is saying that he has issues holding idle when warm...

He should be saving money for a new engine not spending more to get a rotary compression tester.

So, Jared, I’m curious, did you do as the guy suggested and replace the items and run the Fuel cleaner through it and change the oil? Or just rev’ed It and kept driving it? Have had mine for 4 months and am having the same problem.

It's been 7 years, I don't think an answer here is likely.
Sounds like you need a compression test, potentially a new engine. These are the signs.
