casper Posted January 2, 2005 Share Posted January 2, 2005 Our 99 Outback has intermittent code p1507. We replaced the coilpack, wires, and idle air motor. No change. If I stop the engine, the associated misfire and poor idle vanish when I restart. Sometimes we go a couple of hundred miles before it reappears. Has anyone seen anything similar and found the cause? Any help will be very appreciated. Quote Link to comment Share on other sites More sharing options...

Did you try clearing the CEL (disconnect the neg. battery terminal for 20-30 minutes then reconnect) and see if it lights up again? Keep us posted - Ed Quote Link to comment Share on other sites More sharing options...
ShawnW Posted February 28, 2005 Share Posted February 28, 2005 This code would come up if you just happened to have a malfunctioning or disconnected speedometer as well. Don't ask me why I know that. Quote Link to comment Share on other sites More sharing options...
