This morning the check engine light came on, so i took my 05 crossfire limited to advance auto so the could tell me what the problem was. The computer pull up code (P0410 secondary air injection). i call the dealership and they said its probably the air pump or a relay... i looked up the price of the air pump, and its way to expensive for me right now. can anyone tell me is it something that has to be replace asap? and i go a few months without it?
