For the past couple of days my Z has been idling around 500 rpm. I have reset the ECU and attempted to adjust the throttle position using these directions for both - http://www.technosquareinc.com/350reset.htm

However, even after all this it is still idling around 500 rpm!

Does anyone know if there is anything else I can do before bringing it in?

Thanks

 

Lift up battery + over the night.

 

Do you mean to just raise the battery? or disconnect it?

 

Disconnect positive pole.

 

i wish i had that problem! try to get rid of a speratic idle between 1200-1800!!

 

Happened to me before it was the going out fuel pump I replaced the whole unit and no more low idle rpm anymore!

 

Thanks for everyone's input. I will try tcode's advice tonight and let everyone know how that goes. Are there any more suggestions before possibly replacing the fuel pump?
