> It has high NO levels.

> All the normal tune up stuff has been done: plugs, distributor cap, 
> rotor, spark plug wires, air filter, oil filter, oil change.
> 
> BTW my '87 Quattro with 320,000 KM passed with low readings all round. 
> No special preparations except spark plug wires to cure rough running
