nothing worse than chasing down a suction loss...
a near-death experience is just god following "catch and release" regulations...

I just finished the head gaskets on my sister's 3.0.

Vacuum leaks for us too. In my case it was the RH PCV valve hose, it got knocked off at some point, and after the intake was back on it's pretty hidden.

Either way, get a can of starter fluid, and with the engine idling give a short squirt where you think the leak is. If the engine smoothest out or races a little then you've at least found the general area to investigate.

Good idea Dan. I'll be working out several issues at once.

I'm about 90% sure the throttle position sensor is fried. The actual sensing is fine, but the idle circuit resistance does not match up anywhere with the proper readings in the FSM.

Ordered a new one, should be here tomorrow. I'll tackle it again this weekend.
