I have good ones, or you can buy a cheap wire set and use it for parts. > We managed to stick that #1 receptacle assembly back > together; seems to be ok at the moment.

The OE Bosch elbows are great because they are right angle and they screw into the wires, so it is easy to replace just the wire, which is the part that gets old and hard and cracked. The new elbows are crimped on and require that you get new ones each time you replace the wire. I buy wire in 50ft rolls and just replace the wire for MUCH less cost than even an el cheapo wireset. In general, the only parts that you should have to replace are the wire when it gets hard, SP connectors when the resistors go open, and rubber seals when they get hard. Most of these parts will last forever if the cooling system is working, but some can get baked stiff if they get too hot too often. > Found that the manifold pressure sensor hose was disconnected > from the manifold... we may have knocked it off while working on the > plugs, or maybe it was the cause of the poor running.

Use a long screwdriver, blunt end in one ear, to track down the noise. > Jim -- I forgot to check charging system voltage. Sounds like it may not be the problem, but still worth checking someday. Thanks from all of us for helping Lori. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
