RE: Where to get injectors serviced
Strange you should ask, just picked up a set from the re builder yesterday.
Here in the Puget Sound area (Seattle) there are several locations for Dr.
Injector.  Another WetWesties list member had used one of them a couple of
years ago and was impressed.  I took mine to Dr. Injector North in Lynnwood
(two miles from home).  Very impressed, very knowledgeable guy, super clean
and well organized shop.  Four hour turnaround if I wanted it.  $32.50 an
injector, flow tested and charted before and after rebuild.  Included
removing and re installing on the fuel rail and new gaskets, top and bottom.
It will be interesting to see if I notice a difference in performance or
mileage.
