Thanks for the reply. I did compare my connections to other pictures online. It appeared as though I had the vacuum hose from the lower throttle body to the inlet of intake instead of the PCV valve like I saw in some pictures, so I swapped it. I don't know if it really made a difference as I had to change the IAC again because the car did not shut down as it was suppose to when I disconnected it.
Another problem was that I has oil blowing out of the passenger side valve cover, I thought it was the PCV, but it seemed to be coming from the grommet or the valve cover gasket. After all that, it appears to be idling just fine for now. However, it seems as though there is a lot of vacuum. one of the elbows get concaved when the car is on. I am not sure if it has to do with replacing a leaky intake manifold. which got rid my random error codes nd antifreeze leaks.
Does anybody have any idea what tool I can use to remove the bottom bolt,(nearest the strut tower), on the passenger side? I want to replace the gasket eventually, not just the grommets on top. But I could not get the damn bolt off.
