Quick response before I have to step into work- did a lot of reading through the the site yesterday, noticed that standard plenum vacuum at hot idle should be 20 inHg, mine is stable at 8.. so I may have a vac leak somewhere, probably contributing. I have a new VSV2, and nothing under the hood is "custom" I've gone to great lengths to make all the mechanical components as original as possible. Header was cracked bad, currently running a dougthorley, no funky tube, goes directly to Cat inlet. Cat hangs from rubber grommets so I'm sure it is bouncing around a bit, also maybe contributing. my scanner will log/save so I'll pull down the info and post. thank you!! I'll update again asap
