Okay guys- I've got one for ya
While driving, my gas gauge will go all the way across the gauge to empty in a matter of a second and a half. If I turn the steering wheel, it starts to come back up, yet falls again. It seems as if it is a power issue somewhere but I have no idea where to start. Is this a common problem? I am led to believe that it is a power problem because if it were ground, they gauge would almost constantly be at full.
I've got a 1978 K20, Dual tanks (gauge acts the same on either tank) and everything seems to work. Original dash, non tach dash.
please help!
