I had a similar problem with mine. The speedhut gauges work diffrently than the stock gauge cluster for the GM Sonic/Cruise our vanderhall's are based on. I have a few questions.
Do the gauges plug directly into your OBD2 port?
If not, do you have anything else plugged into port? like a anti theft or vehicle tracker or a scanner.
Do you have an aftermarket stereo?
These can interfere with the gauges where you'll only get some gauge readings. Also I would check the data cables that go from gauge to gauge behind the dash, they look like head phone wire/connectors. You can just replace them with quality connectors and see if they make a difference.
