So a new symptom with my Chrysler 1995 Neon.
When the tank gets down to about 1/4 full, (or 3/4 empty for the pessimists out there), it runs better and doesn’t back fire etc.
After filling it up, it starts having the same trouble as before, stalling, muffled sound etc.
I haven’t changed the fuel filter or the fuel pump but that is my next move.
Any advice as to why a car would run better on a close to empty tank?
