Hey guys,

So me and the wife are really stuck here....

Basically we can fire her cobalt up (2008 LT 2.2) we will be driving for like 5 minutes and the car will "jerk" then the RPM gauge just falls to 0 and then doesn't work at all.

The car still continues to run fine after it happens but the rpm needles doesn't move at all and stays at 0.

We pull over restart the car and the RPM gauge works again.

There is no check engine light and we have no idea of what to do to fix it.

Any thoughts or help would be greatly appreciated!
