Guages Acting Up??
 

The fuel, oil pressure, and temp guages have been inconsistent this last week. The temp and oil pressure will climb to near peak slowly, then drop to normal, when this happens I can shut the car off and they will read normal again. The car is not overheating or leaking oil. I don't think the reading is accurate when this happens. The fuel guage also reads higher than it should at times.

What would cause this, I am thinking maybe an increase in system voltage??......perhaps volt. reg??

BTW--86GT, Powerchip, otherwise bone stock

Thanks,

Mine used to do that when the battery was running low... I got the 130 amp alternator, and it stopped.
