At various points had thought to do that but since new parts were installed, (runner boots, TB seal etc.) and all *looked* fine, I made an assumption. Will check further for any vacuum leaks. With the engine lid off, and driving, I can hear a brief whistle sound when throttle moves through roughly the first 1/3 of travel, under load. Sound comes from throttle body area. Will listen with a tube. @ Alistair: yes yes. I know. ;) At this point engine drives ok and I'm being pretty picky. Time to get to other issues like the long heater hoses. They look old!
