Just wanted to post a solution to the problem I was having. Hope this helps someone-

2000 Beetle
2.0 Engine
110k miles

Problem-
On cold starts only, engine would hesitate and fight reving above 2k or going over 20mph for the first 3 min. Engine would then instantly begin working normally although acceleration seemed a tad bit sluggish.

It was so precise that on my daily commute, I could predict within 100ft the spot in the road the engine would start working normally.

The CEL would fire if I pushed the gas too much during this 3 min period.
The code descriptions were
-Cylinder 1 misfire detected
-Cylinder 4 misfire detected
-Random/multiple cylinder misfire detected
-Engine too rich

Attempted Fixes-
New plugs (needed replacement anyway)
Cleaned mass airflow sensor with "MAF Cleaner"
Oil change to check for signs of coolant leakage

Final Solution-
Replaced mass airflow sensor with rebuilt- $104 after core charge refund
Tools needed- phillips head screwdriver and pliers.

To replace, I unplugged the wires attached to the MAF and disconnected a smaller hose with a squeeze disconnect. I then unscrewed the two screws holding the air filter lid in place and used pliers to squeeze open the hose clamp so I could separate the MAF and filter box lid from the intake duct.

Two more screws to remove the MAF from the lid. Replaced with new, reassembled. Temp outside was around 0 degrees farenheit. Car started up and exhibited no hesitation at all. After a few days, the CEL turned off by itself.

Thanks! Info will certainly help someone down the road.
