gauge question

mmvi · January 6th, 2008, 04:49 PM

I start the car, and the gauges tend to max out then go down to 0, THEN they start to work. mostly only the speedo, and rpm gauges. any ideas what makes this happen?

they are just regulating them selves, a lot of cars do it.

Bad ground somewhere?

Did you get it tuned?

Only time mine did that was when I had a lose battery terminal.

it did it before the supercharger, and i am getting my tune monday morning. i've had lots of nice little problems with the installation. as of now, i have ti fix my fuel float, since now my gas gauge doesnt feel like moving. The only thing I am worried about now, is the oil pressure gauge, and the boost gauge. The oil pressure gauge goes up to 45, then moves up to 60, when the car's moving, it goes up to 80ish, but when i let off the gas, it goes back down to 45 or 06 ish. The boost is on vacuum, probably because I hooked it into the vacuum line, it's at 10psi (vacuum) idling in the driveway.

yeah your speedo and and rpm gauge are regulating themselves since there has been a major change to the car, all your gauges need to do it though
