Keeping in mind that for most people this is a week to month long job! -
Its also worth mentioning that 30 years after it left the factory and god knows how many missed oil changes since, there is every possibility that one or more lifters are ticking because they are sticky/gummed up. To resolve that you need to pull the cams then pull each lifter, disassemble, clean, reassemble, soak in oil and re-install, and they should come up good as new. -
What air filter are you running? Is it a panel filter in the stock air box, or a pod filter? Is the air filter the type that is oiled? If you unplug the IACV, what rpm does the engine idle at? -

Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs. -

This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.
