I just put in a throttle body spacer on my 98 SH and now it revs on its own from 1000 -2000 rpm's and goes up and down constantly, does anyone know why its doing this? Could it be that I put it on wrong? I didn't have a lot of time to mess with it after it was on so anybody know what to do?

 

Check the tension in your throttle cable, it could be a bit too tight.

 

yeah either that or is you disconnected any hoses on the intake manifold, your car might not be breathin right

 

The gaskets you get with those things are shitty. Air is probly leaking out.
