Thank you for the reply and info.  The few Chrysler dealers I contacted ran a search and could not locate one.  If you know of any with that part number, I would be happy to buy it.

I have not posted pictures as of yet; I'm still mostly a 35mm guy and downloading pictures is a bit beyond me.....but I imagine my 17 year old son could assist.  Yes, the car is sharp...black with gray leather interior and vinyl top, all powers...you knwo the car.  It's amazing how many people are taken aback by it.  I had a 77 New Yorker St. Regis in its day, and decided that I wanted another New Yorker, as well as wanting to show my son "a real car."  Two summers ago, we flew to Calgary from Philadelphia, and spent nine days crossing the country on mostly back roads.  It was quite the trip.  The car is much more than a car for me.

>IF you're really intent on keeping the Lean Burn system, before you op for a new control unit, check the EGR valve and the vacuum operated heat cross over valve in the left exhaust manifold. You should remove the EGR valve to check for carbon deposits that can hold the valve open.If the poor idle conditions are a lean condition, then feather the choke blade shut very slowly, if the idle improves then you're lean. Thats a carb, EGR, or a possible vacuum leak.It could also be low speed ignition issues with the lean burn.As far as exhaust, any good custom exhaust shop should be able to "Build" what you want. Ya'll have a nice day, Dave.
