My 91 California (with EGR) hatchback runs well, gave 47 MPG at 70-75 on the last long run. Actuating the EGR at idlemakes the car stumble, but not immediately die. Compression read 140, 130, 140 dry; 150, 155, 150 wet. Either the fuel injector or its O-ring leaks, so that starting the car warm, it hits on one, then two, and finally three. It also uses a quart of oil every 1000 mi or so.

I can see that it would like rings and valves, and EGR cleaning is next in line, then the fuel injector issue gets investigated.

Now that I have the 49state 4door, I could disable this one without having to walk for groceries, but am reluctant to tear into it, as everything is old enough to vote. I have a can of Seafoam, so I'll do that after it's back together from the EGR reaming.
How do others decide about one that is clearly due, but still "works fine"?
