Surging Issue... at idle and when driving. arghh.

It most likely is a bad throttlebody switch or wiring to the switch that is causing
this.

Was having some cold starting issues (wouldn't hold idle and would stall
sometimes).   Put in replacement ISV and all was well again... been just
over a week since putting isv in .   Just now car started to 'surge'. it
will idle up and down rapidly at the lights... and will surge even driving... up/down
up/down.  WHen you upshift the revs were not dropping recently (ie: seemed to be 500rpm
too high...revs didn't fall off)... now they actually increase.

Undid the ISV...no change.

Any thoughts? I'm at work. thinking to leave early to avoid traffic and try to fix at
home. (although I have lots of spare parts in my car right now for some reason)

Thanks!
