    New to forum need expert advice from current gp owners. Failed emissions due to code p0411 air injection system. Changed air pump still have code issue. Don't know what else it could be, and running out of time for registration. Please help if you can.

    http://www.obd-codes.com/p0411 pretty sure theres a valve that needs to be changed. most delete it and have the codes deleted with a tuner when they can.

    unless your in ca and need to have it.
