My car has been hunting for idle and dying at stop signs. It's not doing it all the time, but it seems to be happening more often. I smoke tested it to look for a vac leak and smoke came pouring out of the back of the motor underneath the plenum. I'm pretty sure its the PCV assembly and from the looks of it I'm going to have to R&I the intake to get to it. Before I spend anymore effort on it, does anyone have any thoughts? This motor isn't as easy to work on as my 4.6 was.
