I did about 1000 miles of holiday driving this past weekend and on the way home my CEL came on. Ran it over to Autozone and they read off two error codes for me. P1404 and P0402. Looked them both up and they seem to be associated with the ERG. Anyone else run into these two codes? If so, what did you do to rectify the situation? I would really like to take care of this myself as I really don't want to deal with the Isuzu dealer here in Austin. Thanks in advance.
