My thoughts exactly. I checked as many of the vac lines I could find and thought I had nailed them. I took it to Ford today to get a diagnic check on the sensors and they called to say the
PCV valve was faulty. A bit strange seeing as how I had checked it the day before and it pushed air one way and blocked air going the other, but I took their word. They broke the gasket for the upper inlet manifold so I wont know the result until tomorrow when a new gasket comes in.
Heres hoping!
Thanks for the reasurance concerning the vacuum leak. I was pretty sure I was looking in the right place, but not quite 100%.
Regards,
Scott.
