I bought truck 12/5/12 at night while setting up the On Star features the idle was rough and the Rpms where irratic. The person helping me operations and description of options also noticed this. We though it was normal after all it is brand new and may need to run longer to sycronize the sensors and OCM. 200 miles later this truck has a OCM learning challange.
