Possible vacuum leak, PITA to track down...Most likely something small



Well this morning after work I stopped down at the shop and talked to the head mechanic about what I learned on the internet with vacuum leaks, etc. He said he had already done a good check for this.

When I got home I did the starter fluid check anyway. When I sprayed in the vicinity of the PCV valve (behind the throttle body) I got a slight RPM increase. I found a nice little 1/4 inch cut in the hose that leads to the PCV! Put my finger over it and the car almost died. Took the hose off and getting a replacement today. I'm hoping this is the problem.
