Thanks Arthur, I knew you would set me straight....
Your knowledge of these cars has been a big help to me in the past and continues to be now. Now what in the heck is the AIR you mention for code 4? Also the cam solenoid (18) is that the one that is attached on the front of the head? If that cam solenoid was bad, would that account for the feeling of the car running advanced than retarded?
Thanks Arthur, you the MAN!!
