Trent,

Does this mileage drop occur at all times or is it seasonal? If it's seasonal
(ie. with the cold weather) I would suggest you see if your thermostat is
stuck open or been removed by a PO. This will hurt your mileage, but I'm not
sure it would be the only cause.

A good reference would be Bosch Fuel Injection & Engine Management by Probst.
While it won't necessarily have all the answers, it has helped me understand
FI systems.

Good Luck,

Paul 89 Carat 147K (waiting an engine transplant decision)

<< Hi!

 I was referred to you by Kyle at VW Motorsports.  He suggested I tell you my
 problem and see if anyone has any suggestions.  I have an '84 Westy.  It's
 an Automatic.  Everything is OE.  It has a new ECU, new exhaust, recent oil
 & fuel filter change,  clean injectors, etc.  It only gets 11MPG!

 It seems to take about 25min. for the engine temp gauge to reach halfway on
 the dash.  This is the highest the gauge ever reads.  Is this normal?  I
 have been told that I need a new coolant temp sensor, ecu, 02 sensor, and
 thermostat.  I have had estimates from $18U.S. to $325U.S.   Every place I
 go tells me something different but I get the feeling that they just want my
 wallet.

 I live in Regina, Saskatchewan, Canada so good VW knowledge is hard to come
 by.  Any suggestions would be greatly appreciated.

 Thanks,

 Trent Wessner
