Mine started doing something similar tonight, won't start unless I flutter the accelerator, won't idle or accelerate for s**t but runs ok over 2500rpm. Economy/vacuum guage is pegged in the red at idle and sits about mid point once the car gets rolling. Vacuum loss at idle is enough to deplete the power brake assist, but builds back up when moving again. I limped home from work tonight, but I'll be driving the Stealth until I get this figured out.
