I believe all Civic/Teg fuel gauges are similarly odd in that respect. The plummet very quickly and take a good while to raise back up. I have had 3 different gauge clusters in my civic (2 civic, 1 integra) and when I toss it around a corner or am experiencing a hill, the fuel gauge will drop substantially and rather quickly. When I level back out, it takes a few seconds for it to creep back up to position. I think it's just the way the sending unit works. :dunno:
