Two days ago my car threw a check engine light, cleared the codes and it came back on this morning after driving it and putting it in idle.
Bit of context, went shopping and the car was driving fine.
When I returned and started the car, RPM was slightly higher than normal, and the car began to shake lasting maybe 10 - 15 seconds.
RPM carried on rising slowly until I tapped my accelerator which brought it straight back down and car idled however was louder than normal.
Scanned for codes and these are the codes returned:

21A02D - Combustion Control: Idle Irregular
213601 - Power Management: Standby Current Violation
118401 - Mixture Control: Mixture Too Lean, Deviation Too High
118001 - Mixture Control: Fuel-Air Mixture Too Lean

I read somewhere that it could be caused by failed sparkplugs however although I haven't checked them they were replaced around 4 months ago.
Car feels heavier when driving, also seems like it takes a lot more to get some power into it.
I think there is a very light hiss but it could also just be my mental paranoia and really its just the sounds of the MST intake. Car is running stage 1 map.

Any thought or help would really be appreciated!Two days ago my car threw a check engine light, cleared the codes and it came back on this morning after driving it and putting it in idle.
