<x-flowed>Actually yes I have, or at least I have the majority of the issues fixed. The miss I was experiencing weas caused I believe by a number of issues. A couple of the valves were very tight, no gap at all when it was stone cold, and I had some loose connections to the injectors. Thats all been taken care of now though. The only issue I have that remains is the fact that my idle wont adjust above 850. It lopes a little at idle, sounds worse though because I have a heat exchanger that is a little corroded at the rear connection. The heat exchanger isnt even close to sealing properly. I plan on checking the fuel pressure and the system voltage this weekend (along with dwell, timing, plugs, oil change, etc.) as those are the two things that I have yet to check into fully. >From: "Roush, Norman" <norman.roush@compaq.com> >To: <vw_type3@hotmail.com> >Subject: FW: [T3] 72 square, rough idle, #1 missing? >Date: Thu, 28 Mar 2002 12:16:30 -0800 > >Drake, > >Did you get your rough idle, #1 missing problem cured?
