The last few days my fuel guage has been doing some funky things. Sometimes if I am just sitting still at a light it drops to E and my check guages light comes on but as soon as I start moving again it comes right back up. Sometimes when I start the car the fuel guage will be very slow to come up to the lvl that the fuel is at and sometimes it wont come up at all until I start moving. Is this just the sender in the tank or something else do you think?

 

hey man i got a 1994 z28 and its does the same thing. did u figure out the problem?

 

I would say that its a corrosion problem with the wires. At idle the alt. isn't producing much voltage. But when your driving voltage increases. Just something to consider.
