re. disintended nondeceleration....

[jim rose]

i cleaned the ISV last night (couldnt believe the seemingly endless amount 
of crud that i gumout-ed out of it) and tightened / checked every vaccum 
line in the western world for leaks/crakcs etc. as well as played with the 
linkage, and tightened the adjuster bolt to the discc-shaped vaccum 
controller (1/2 rubber, 1/2 metal about 2.5" in diameter - what IS that 
thing?) as the linkage was loose.

alas, to no avail. off to look at /check the switches. thanks for all 
advice, ill post up when i get it sorted.

i never knew how much i used the engine to slow the car till now.
