Re: Fuel Range Indication -Reply

Just wanted to put in a quick $0.02 on the fuel consumption sender.  When 
I bought the '88 5K TQWagon, I managed to get a couple hundred $ from 
the seller because it didn't work.  Apparently he had someone replace the 
computer recently as well.  Well ... not being shy about getting my hands 
dirty, with a Bentley in my hand I looked into the problem.  There is a 
variable resistor connected to the airflow sensor that provides the fuel 
consumption info to the trip computer (and apparently is used nowhere 
else in the FI).  I opened up the airbox and managed to get some resist-
ance change by playing with the wiper, forcing it against the resistance 
element (all of this was done blindly since I didn't have a mirror & lamp).  
The fuel consumption started working;  it reads high, but closer.  (I 
wish I was getting 37.8 MPG on the freeway!)  My friend in the parts 
department told me that the resistor is not available by itself.  When I 
have a chance, I plan to get a better look inside and see if I can make it 
work better.  I'll let you all know when that happens.
