Spazzaroth Posted July 15, 2021 Share Posted July 15, 2021 Over the last few months my MPG has gone from about 26 down to 14. Car still runs. Idle is a little rough but I drive it locally. Any idea of things I should check? Link to comment Share on other sites More sharing options...
2seater Posted July 15, 2021 Share Posted July 15, 2021 Check the vacuum connection at the fuel pressure regulator for evidence of fuel in the hose and check the O2 sensor activity and cross counts in diagnostics 1 Link to comment Share on other sites More sharing options...
Barney Eaton Posted July 21, 2021 Share Posted July 21, 2021 nonfunctional cam sensor will hurt mileage and performance. Link to comment Share on other sites More sharing options...
EmTee Posted July 23, 2021 Share Posted July 23, 2021 Check all of the vacuum hoses connected to the engine. You'll likely find one split on the bottom right where it attaches to the hose barb. The computer sees low vacuum/high pressure and starts dumping fuel to compensate... Link to comment Share on other sites More sharing options...
