I took my Cobalt to the dealer this morning and they did all of the repairs. Here's a list:

The gauges would not work and the Display would read "power steering" and "low fuel". The gauges would then go down to zero. But would eventually reset themselves. But enough rambling, they said that it was "Out of Calibration" and the part was "Powertrain Control Module Engine" "Reprogramming with SPS" and "reprogram IPC"

I'll give it a go for the next few weeks and see what happens. What do you guys think?

 

it happens with these cars unfortunatly....
