Dan -
You should learn to do some of the diagnostics yourself. Most shops will
just keep changing things and guessing just to run up the bill. I started
doing my own diagnostics when i realized it's cheaper and faster to
understand this stuff yourself. Trips back and forth to the mechanic are a
pain in the b***.
Take your car out on the highway and when you get up to speed and it starts
missing lot, immediately turn off the motor and coast to a stop (ideally
pull off an exit on the freeway). Take the tops off the fuel chambers and
see if there is fuel in both bowls. At highway speeds both bowls should be
full of fuel, but if one or both are empty then you know it is a fuel
problem.
I still think you are having a fuel delivery problem. They didn't check
your tank and they didn't swap out your fuel pump (and filter if you have
it)... they didn't do the things they are supposed to do. You can have
partial flow and if they turn on the ignition in the garage and then check
the float chambers it won't tell them anything because they will be full of
fuel.
