05 cobalt speedometer problem
Hello all, i looked all over the place and cpuldnt seem to find my problem already resolved so here goes...
I have a 05 cobalt LS with the 2.2
I got in it today after changing a coil pack and the speedometer was at 60mph when the car was off. While driving, the speedometer starts at 60 and goes up. As if 60 is the new 0mph mark. So at 40 it says 100 etc. I am baffled. Please send help. Thanks.
