I just went on a 400 mile trip.  My ol friend started to stutter a bit
aroun 60-70 mph.  back off,  55 say, and run fine.   I pulled off the
road and took my air cleaner duct off in case it was n't getting
enough
air.  Got back on the road, ran fine, high speed, for about 20 miles,
then statred the miss again,  this time, couldn't make it go over
60mph.   Got to my destination,  200miles, then 5 hours later left to
go back home.  The car ran fine the whole trip except for a couple
time
i felt a faint miss.   Not a sign of an injector pump going is it?
Will replace fuel filters first, but they are not that old.  I have
put
near 30k on this car since a rebuild of the injector pump.   I
appreciate all the help you guys give me.  -gar

I would run a bottle of Techron through it. Sounds like you may have
gotten some bad fuel to me.

Fuel starvation, suspect the filters and remember there's pick-up screen
inside the tank. Could also be a plugged fuel tank vent that, after some
long driving, creates enough vacuum inside the tank to impede the fuel flow.

Sounds like fuiel starvation. Really - check the fuel filters. If
they're full of black crud and you're in a warm climate you have algae.
