Hi everyone. I've been following the thread about the relationship between the throttle body and poor idle (I hope i have that right?)

I'm wondering if my lousy idle is the same as what others have experienced.  I took two short videos that I was hoping someone more knowledgeable could take a look at.

Is it easier for me to email the video or to post it to youtube or something?

You can see that it surges a bit (100-200 rpm in this example, sometimes a bit more) when the van is in Park.  Drop it into gear and all is well.

I have a 1985 automatic with a 2.1L Boston Bob.

Thanks as always
Jeff
