I stole this pic from Tuners but mine is broken exactly the same. Ziggy doesn't seem to carry these so I'm hoping someone did an ERG delete and has one of these in their parts bin. It's the valve with two attached vacuum lines sitting under the upper rad hose on a 1g thermostat housing.

Call mopar or mitsu. I got mine for $40ish bucks 2 years ago.

Thanks Stephen, that's a better price than I expected and it will do. I had stopped buying anything at a Chrysler dealer after a couple of tiny dash light bulbs cost me $9 each.

And thanks Gui, I was aware of that link but only buy stuff from the states when the order is large enough to be worth it.

Try them both. I think one was cheaper then the other.

Chrystler is usually cheaper

Mine broke too when I was doing EGR and I just left it.
