My 87 GN has aquired a problem that I haven't been able to track down and need some help. When its first started it runs well at first. Shortly after start the idle degrades and gets to the point of almost to die but then picks back up. But then goes back down. This carries on till warmed up slightly. The car seems to run normal after warm up.
This car has 27k and had been sitting a while before I picked it up.
Any help would be great

This *may* indicate the IAC being dirty or out of adjustment. Also may indicate the throttle plate being too far closed. http://www.gnttype.org/techarea/faq/IACresetscan.html may correct this.

Do you have a scan tool?

The IAC was reading wrong and would not stay in adjustment. I removed and cleaned. All readings consistant now and idle seems fine. Thanks
