Ok comming to a light and it still hangs at 1500 then goes down to about 900. This sucks, After new heads/cam/intake/TB/injectors/mass air. All of that and cleaning the 10 pins and tweeking them, plus doing the reset of the computer It still hangs! How come??

I don't have the VSS hooked up, When I did the mass air conversion it said optional. So should I hook it up?

Yes, otherwise the computer doesn't know how fast you're going, e.g. has no idea you're coming to a stop. I don't know what it does then, maybe times out and finally comes down? Not sure but it couldn't hurt to hook up the VSS and see what happens.

I have this same problem after my head, cam, intake install and I do have the VSS hooked up. I have tried all the things to correct this and nothing has been successful. Anyone have any other ideas maybe I havn't tried?

If it just sticks at around 1500 or less and then drops down when you are stopped, then you probably are running an idle plate and need to adjust the screws. If it does this driving down the road, where say you are at 4k then push the clutch in to shift, and it hangs at 3500 or so and sometimes stays there unless you get back in gear and slow down, or restart the car, then its your 10 pin connectors at the back of the intake....clean them by connecting and disconnecting 10-20 times, then use some dialectric grease inside. Hook up the vss, its designed to hold the rpm up a tad during shifts to easy the drivetrain.
