Today for the first time I noticed when I'm at a stop(in gear with foot on the brake),my oil pressure gauge was at just above zero. When I stepped on the gas it went immediately in between 2 and 3. I observed a week ago that during the same conditions the settings were (1 when stopped or slightly above) to 3 when I stepped on the gas. Can anyone tell me what problem(s) I am getting ready to encounter, and how much should I be prepared to spend. The car has 193k mi. on it and it runs great. Does this sound like a oil pump problem? HELP!!! By the way, the car is a 86 300E
