I have a 1986 Pontiac Parisienne. Mechanically it's in great shape runs really good, but there is a couple things that have been getting on my nerves, and that is the gas gauge and the gearshift indicator. The gearshift indicator is stuck in the Park position. That doesn't bother me so much but I would like to get it unstuck. The thing that is really grinding on my nerves the last year and half is the gas gauge indicator. The gas gauge does move and works fair when I've got over a half a tank. However, when it gets below a half of a tank it seems to have a mind of its own. Sometimes it registers properly and sometimes it does not. When it registers E when I know it's got a quarter take more, if I take the butt end of a screwdriver and bang on the dashboard sometimes it will register correctly and sometimes it will not. Anyone have a suggestion as what the problem may be? Do you think the problem may be originating with the sensor in the tank, or do you think it's just perhaps the spring on the gas gauge needle? Does this seem like a problem that a weekend mechanic may be able to fix fairly easy, or is this going to be a little bit more involved? Would it be a fairly simple task to install an external gas gauge and just forget about trying to fix the old gas gauge on the Car? Anyway, hit me with what you got I am just looking for suggestions on the simplest way to solve the problem.
