This report contains an analysis of the results of Federal Test Procedure (FTP) emissions testing of 98 1979 model year California vehicles that had accumulated between 40,000 and 50,000 miles. The vehicles were procured from the general public and represented the largest selling models and engines marketed by the major domestic manufacturers during the 1979 model year. All vehicles were screened for proper use and maintenance. Also, prior to initial emissions testing, minor control system disablements and engine parameter maladjustments were corrected. Although some differences exist, the screening criteria and program protocols were such that the test results are comparable to present recall surveillance testing.
