My cor (curcuit opening relay) is acting up, it makes a clicking noise sometimes when I am idling, when that happens the truck threatens to die, just curious if anyone else has had this problem.

 

pull it apart and clean the contacts. Your air flow meter sends a signal to the Cor to kick on the fuel pump. IF there is a problem with the flap on the meter or possibly not enough vacuum from the motor to keep it open then It will do exactly as you describe.

 

thanks vital, I will take that apart and clean it, does your 2 1/4" exhaust increase your gas milage?

 

Not really. It gave me a little more umpf at the top. But I'm 2 1/2 now with a supercharger.

 

Well, we did not want to go down Waipio in with a gimpy part, so I went ahead and bought a new cor, it ran 108$, no more clickety click.

 

Glad its working great now.
