Re: [T3] 72 square, rough idle, #1 missing?

["Drake ." <vw_type3@hotmail.com>]

<x-flowed>What I have in mine is definitely not factory. What someone has done is 
create a length of "wire" that contains roughly 8 butt splices, inbetween 
most of the butt splices there is a SHORT length of wire (perhaps a 1/4 in 
of wire visible between the butt splices) There are 2 or 3 resistors in 
between some of the butt splices vice wire. I forget now what the reading 
was but I think the total resistance of this section was somewhere like 1.5k 
ohms.

>From what I was reading on the D-Jet system (somewhere) I thought that 
adding resistance to the head temp sensor enrichened the mixture all the 
time. There was another temp sensor that you needed to add resistance to 
enrichen the idle mixture only.
