Answer 1

P1004 Short Runner Valve control performance

This is more than likely will be a intermittent code condition. One of the job for the ECM is to look for open shorts and grounds. There are soft codes and hard codes, soft code condition are intermittent condition, Hard code condition reoccur most immediately. If this code up immediately you will need a SRV (short runner valve) assemby.
