Possible vacuum leak located! Hole on passenger side of intake plenum was sticky taped over instead of an alan bolt in it. What the crap! It was kinda hidden behind my fuel rail. Too late now to see if it was the culprit.

By the way, this was my stupid mistake! When I intitially installed everything I didn't have an alan bolt so I used some foam sticky tape to allow me to start the car and adjust the idle/timing etc. This was a little while back and I'd forgotten about the bolt even though I had bought one. Anyway, it's put in place now, I just need to go on a test run to see if it cures my problem. It may snow tonight! ERRGHH!
