I recently posted that I was experiencing a problem with my transmission on my 95-3.1. When I was at cruising speeds up to 65-70 or approching a slight grade, I experienced a "chuggle" or thumping like hesitation that felt like it was coming from the transmission. After checking vacuum lines , TCC wiring connections and reading and re-reading threads on the Torque Convertor Solenoid ,etc, I finally got the opportunity to change my fuel filter. Lo and behold, no more chuggle! the old filter (car has 103K miles) was clogged completely, I tried to blow throw it but could not..( could blow through new one easily) my Lumina was starving for fuel! I wonder how it ever ran but it did. Idled fine, accelerated good, just had the "chuggle' when at speed and needed more fuel...hmmm..Occam's Razor once again.

Now free of restriction, your fuel pump will self-destruct. Occam's razor has nothing on Murphy's law. ;)
