Default 2010 VW Tiguan cylinder misfires

I have the check engine and EPC lights on. Recently changed spark plugs and coils. Took it to Autozone and it says "Code P0300 indicates there were too many random cylinder misfires within a predetermined period of time" in addition to cylinders 1, 2, and 3 misfiring. They told me to inspect for a faulty vacuum hose, any ideas where I should look for this? Any advice is appreciated, thanks!

VAG Error Code: 16684/15137/10203/4051/000768

EOBD II Error Code: P0300

Fault Location:
Random/Multiple Cylinder(s) - Misfire Detected/Upper Limit Exceeded/Implausible Signal


Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.

Wiring/Connector(s).
Air Intake System leaking.
Fuel Supply faulty.
Injector(s) faulty.
Ignition Cable(s) and/or Spark Plug(s) faulty.
Ignition coil(s) faulty.
Exhaust Gas Recirculation (EGR) Valve (N18) stuck/open.
Camshaft Position (Hall) Sensor (G40) faulty.
Low compression.

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Check Misfire Recognition.
Check Air Intake System.
Check Fuel Supply.
Check Injector(s) and Injector Sealing.
Check Ignition Cable(s) and Spark Plug(s).
Check Ignition Coil(s).
Check Exhaust Gas Recirculation (EGR) Valve (N18).
Check Camshaft Position (Hall) Sensor (G40).
Check cylinder compressions.

Special Notes:
This Diagnostic Trouble Code (DTC) indicates that one or multiple cylinders are misfiring, but the Electronic Control Unit (ECU) fails to identify the cylinder.

Tech Notes:
The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persist more tests needs to be done to diagnose problem.

When is the code detected?:
The control module monitors the crankshaft speed and has detected a misfire condition.

Description:
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Engine Speed (RPM) Sensor (G28)/Crankshaft Position Sensor (G28) signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.
