You could have broken the porcelain on the new plugs when in stalling them.
If you used a different type of plug like iridium your coils may not fire them properly.
The gap could be off. Not uncommon for them to have been dropped and bend the tang during shipping.
Could have damaged the old wires or didn't get them back on in the correct firing order.

Did you set the gap on the new plugs to factory settings before putting them in? If not, they may not be the right gap.
Also, any number of other issues are possible such as:
1. Wrong plugs
2. Damaged wires when removed from old plugs
(Plug connector wires can be easily damaged when removing from old plug if just pulled off and special tool isn't used.)
3. Stripped threads on plug allowing gas blow by and poor compression.
No. (2) seems to be the most likely cause without knowing anything else. A new set of ignition wires after 15 years of service is not something frivolous to do and money well spent.
Thanks. Put old plugs back in and running fine.

Try a new different set of plugs
May have plug wires wrong
Check wires are correctly installed in proper firing order. Confirm gap is correct and install new spark plug wires making sure witted are clear of any sharp or hot engine parts
Are you sure you put leads back in proper order.

Check the plug gap is correct for your vehicle because they are auto set but a small difference could make it miss.
Alternatively perhaps the mixture settings were altered for the old plugs .

The cylinders are numbered as on the spark pack you changed. You might have done better putting the seafoam in the tank as an injector cleaner. Not sure why you changed so many parts, you seem to know how to get the codes from test connector lead hookup and the blink pattern. You might also want to check the fuel rail pressure and the crank and cam angle sensors. Before replacing the injector, swap the #4 injector with the adjacent one and see it the code moves with the injector or stays put. If the code stays on #4, then check the injector wiring, if it moves clean or replace the injector.
SOURCE: What is the recommended mileage to change the
It is recommended to change timing belts and tensions between 50 to 70 thousand miles. Hope this helps.

I would replace the spark plug cable as well. It is quite easy the damage old plug wires when removing them to change the spark plugs. A good way to check this is to pull off a spark plug wire (one at a time), then start your car. If it became worse then move to the next wire until you find one that is causing the miss. Make sure you shut the vehicle off before touching the wires. Then switch it out with one of the other wires. Make sure you change it at the coil as well. Now recheck for the miss. If it moved then it's the wire. If not the you might need to recheck that plug gap and also inspect the inside of the distributor cap. You may need to replace that as well.
Plugs, Wires, Cap and Rotor should really all be replaced at the same time.

Sounds to me like you may have left the air temp sensor or something electronic disconnected - Distributor - MAF sensor - go back and check and make sure that there's not an electrical pigtail somewhere hanging off - a vacuum leak wouldn't keep it from starting unless it were major - and your AUDI is mechanical injection I think - so fuel pull isn't a problem - check those connectors - let me know??? Thanks
