T3: Re: Bucking (was: Pressure sensor)

[Steven Ayres <comwest@well.com>]

JohnC=> slight 'bucking' or 'hesitation' while accelerating, and a 
     => little off feeling while cruising. Gas mileage is down 

I'd say leave off component checks until you've had time to look very 
closely for a bad ground in your FI system. A loose screw or connector, 
dirty contact, etc., is your likeliest culprit.

I had a couple of almost stripped-out sheet metal screws in my FI Bus 
that left me stranded by the road not too long ago. The early symptoms 
were *exactly* as you describe. I determined (only in hindsight, of 
course) that the bucking happened more often during acceleration 
because the part that needed grounding was being pushed away from its 
ground -- the ground would open, the engine would stop, we'd stop 
accelerating, the ground would close again, and the engine would restart.
