[urq] The WX is acting up again

[daniel dornseif]

I am wondering if anyone else has seen this:  My '83 has been running really well lately until last week.  Occaisionally, the car will start to run rough (generally coming off of low throttle or idle) and will hesitate (or stall if I take my foot off the gas).  If I floor it, generally it will come back to life and run normally again.  During one of these episodes, while I push on the gas the boost guage shows positive boost, but the car doesn't accellerate for about a second or two, then bam...it takes off.  The other symtoms during one of these fits are backfiring (occaisionally) and a jumping needle on the tach that do not jive with actual engine speed.  Since the car is only doing this every once and a while, trial and error is difficult. Onset has occurred with the motor both warm and cold, and at idle or at freeway speeds.  The only thing that seems consistent is that it starts at a low throttle setting and heals itself after a time a full throttle.  It was suggested to me that
 it might be a blockage/sludge in the fuel tank, which is certainly possible, but I want to try out other ideas before going to the expense of having the fuel tank redone.  I am wondering if the O2 sensor, or Ignition timing signal could cause this type of behavior.  At first I was thinking fuel mixture, but the fact that I can get positive boost leads me to think that it is probably getting fuel.  I dunno!  Any ideas would be most appreciated.  TIA,
