rringeisen Posted February 25, 2004 Report Share Posted February 25, 2004 I have 1 1976 Eldorado with the 500 efi engine and I am not able to correct a very rough idle. My mechanic has reviewed / replaced most of the fuel injectors and rails but the problem persists. Does anyone have any ideas? Link to comment Share on other sites More sharing options...

KevinW Posted February 25, 2004 Report Share Posted February 25, 2004 I have 1 1976 Eldorado with the 500 efi engine and I am not able to correct a very rough idle. My mechanic has reviewed / replaced most of the fuel injectors and rails but the problem persists. Does anyone have any ideas? How does it run aside from the poor idle? A common problem on the early EFI cars is failure of the temperature sensors; they should read about 1000 ohms at room temperature. ___________________________________________________ Link to comment Share on other sites More sharing options...
rringeisen Posted February 26, 2004 Author Report Share Posted February 26, 2004 Thanks Kevin - it runs very well once it has warmed up - highway driving is great. Link to comment Share on other sites More sharing options...
KevinW Posted February 26, 2004 Report Share Posted February 26, 2004 Thanks Kevin - it runs very well once it has warmed up - highway driving is great. As I recall, their resistance increases with temperature (unlike newer thermistors); an open circuit would force the system to run too lean, which might explain the poor operation during warm up. ___________________________________________________ Link to comment Share on other sites More sharing options...

Ranger Posted December 27, 2007 Report Share Posted December 27, 2007 Have you checked the fuel pressure? Link to comment Share on other sites More sharing options...
