I would guess it means the rpms are going up and down. :shrug:

Have you checked for vaccum leaks?

yes at idle it hops from 1500 to 3500 or so... where can i get a vacuum diagram

You could try here. www.celicatech.com
I dont' have one myself.

To see if you have a leak, with the engine running, spray brake cleaner around anywhere you took apart that has to do with the intake system.
Also, try around the vaccum lines.

Don't use too much, it's not good for the rubber.

[fredk]

are you telling us that it runs 3500k without your foot on the gas?

[Project_ST184]

if it idles at 3500 that is not a good sign.

Most likely vaccum leak.

Try adjusting the TPS sensor.
This happened when I swapped a 3sfe for a genII 3sge. Turned out the throttle position sensor was slightly opened.
