July 11, 200916 yr Working on a 92 Legacy. The gas gauge goes down to empty when the car is started, and after a minute or two goes back up to where ever it was before the car was started. I'm thinking its just a corroded wire on the sending unit. Am I going in the right direction?
July 11, 200916 yr There is a voltage regulator in the circuit I believe and the trouble may be with that.
July 16, 200916 yr Do you have any issues with the guage while driving, or only after startup? Does it happen at cold starts only?
