Idle issues 850 1994

Hi everyone,
I'm encountering a problem with my 850 and an open to any thoughts on what may ne causing this. My car was laid up for several months after a fuel pump failure. Now that winter is approaching I put my other car away and have been working on the 850. I replaced the fuel pump. Due to difficulty gettin the old one out I had todrop the tank in order to replace the pump. The engine fires but only stays running while I rev the engine. As soon as I lift the throttle it stalls. The car ran fine before the fuel pump failed. Are there any thoughts on this? Any input would be greatly appreciated.
Thanks.
Joel

    Idle air valve stuck. Sometimes they can be cleaned up. It may only be the electrical connection. It is the gadget mounted in rubber next to the throttle body. Remove the plastic cover from the throttle body and you will see it.
    Good luck.

      Hi TomL,
      Thanks for the advice. It's getting there. I cleaned the contacts on the IAV. Also noticed that the large air inlet tube going from the rad support to the Airbox was disconnected so this may have contributed to the issue somewhat as well.
      Anyhow the car now holds an idle for a few seconds then starts to surge at idle from 500 to 1000 rpms for a short time and then stalls out. The culprit may be the IAV. I'll test tomorrow.
      Thanks again.
      Joel
