87 Hunting at Idle
Has anyone had any experience with this issue? The idle speed tends to jump around a lot at idle. I was thinking TPS maybe?

Re: 87 Hunting at Idle
Yea could be your TPS or it is sucking in air from a crack. Try spraying starter fluid near the intake if it revs then that could be the problem. Next I would consider the TPS or Idle control vacuum last.
