well i finally got my car back on the road last weekend. been driving it all week. there have been some codes but just haven't gotten them checked. so a couple a days ago i realize that my car is idling really rough and isn't feeling right. so i went to Autozone for them to check the codes for me, since the dealership is closed.

P0300 Misfire code & P0315 Crank Sensor code..... the print outs from Autozone say the description of the codes and what are possible causes.

i just wanted to know if anyone has experienced these codes at the same time, if so what was done to your car to fix it?

i have a 2006 Chevy Cobalt SS/SC, completely stock.
