My Miata hasn't been starting up for a few days but it finally did some how but is running poorly

Video of how it sounds like:

Can anyone decipher whats wrong or could be wrong from the way it sounds?

Already checked:
Fuses good
Fuel pump works
I have sparks
Timing belt looks TDC okay to me from what I've looked at and read online (maybe it still might be off?).
Checked for codes, no codes

Haven't Checked:
Fuel pressure
Compression

Engine has 139,000 miles.

check the IAC and the TPS. i had that and thats what it was. but it could also be the maf sensor if its not getting the right voltage or if its just going bad

sounds like it's turning slowly. how's the tension on the belts?
what's it idling at?

Bad coilpack? I fried mine after doing a compression test... apparently there is a special way for miatas that I was unaware of.... haha...

then again... I got a check engine light when that happened...

Have you adjusted the idle speed by shorting TEN/GND with all accessories off? It should be reading 850RPM.

sounds like mine when it slipped a bearing. have you unplugged anything off the engine?
