Sounds like a leaking injector or two.  Check for that, or just have them
rebuilt, it's about time.

Subject: Poor gas Mileage

My 84 Westy w/ original 1.9 gas engine w/ 155K on it has been getting poor
gas mileage on it since I got to Maine from Utah. I have had it twice into a
local Larry Chase approved VW Repair place & had it tuned up per their
suggestions, new plug wires, plugs, rotor, cap, fuel filter, etc. but I am
still getting 11-12 mpg where I used to get 16-18.  It seems to run fine,
but mpg is killing moi.   After running for awhile, the rpms seem to surge
100 rpms up & down . Any suggestions?

YMMV,

Mr. BZ-mine do
