Well, it finally happened.
After 19 years, the check engine light came on for the first time ever, accompanied by a cylinder miss. Diagnosed the problem to be a stuck fuel injector.
Went to the junker to get a rail with 3 injectors; they are not easy to take out from the fuel rail, much less at the junk yard. Tested the injector on the vehicle again... stuck. Removed it. Tested it on the bench and appeared to be working. Put it back on the vehicle, and it has been working perfectly ever since.
Go figure...
Do they make cars that work so well for so long anymore?
