Abstract
The report describes the results of an exhaust emission testing program in which 24 relatively new vehicles sampled in a Restorative Maintenance Program in Denver were retested approximately one year later. Many vehicles had experienced maladjustments and disablements even though the owner reported that he felt his vehicle had been maintained according to the manufacturer's recommendations. Reductions in average emission levels followed the correction of the maladjustment and disablement actions to a point close to those after the prior tune-up. Modest fuel economy improvements were noted this year, probably due to the fact that the vehicles had overcome the 'green engine' effect.
