It was the breaking down of the vacuum pump that caused wild smoke.
No idea what was exactly happening. Even with the broken vacuum pump and the smoke the engine sounded OK (minus the rattle of the broken vacuum pump, which still produced vacuum).
When I got the car back from the mechanic, it was nailing hard, had no power, smoked like a wild west iron horse. It has improved, but power is still bad.
No idea what caused the injectors to clog up that quickly. I'll go for a cleaning first, and if this doesn't help, for a timing adjustment of the injector pump. (The mechanic took the timing chain off. No idea what he could have messed up).
Your advice, Zedd, is very much appreciated. Especially with the mechanical cleaning of the injectors and the pop testing.
