T ing into the vapor line to the pcv was a big mistake.
The Vacuum the PCV pulls is excessive, the engine "thought" it had a vacuum leak, your lucky it didn`t run so lean it burned a piston or valve. I`ve been trying to do this same thing with my 86 Cutlass, if I plug off the vapor line, I have all kinds of fuel pressure problems, excessive high pressure is the result, but if I leave it open and park the car all you can smell is gas. When I did this I used a orifice with the smallest hole drilled in it possible, it still pulls so much vacuum and makes the fuel cap make a noise from the vacuum being pulled through it. so I would just recommend you run the vapor line to the air cleaner, so it`s not being pulled by a high vacuum source and won`t cause any problems elsewise.
