great info on this board!
here's my problem with my 97 900se turbo 2.0L convertible with 72K miles:
currently getting P0172 CEL(system too rich codes, logged by Drive Right Car Chip)also takes a long time to start (over a minute..longer if it has been sitting for awhile)..once I get the engine started seems to run fine. started to change out parts a couple of months ago when she started to missfire under load(CEL P0300)and unpredictable starts (cold or hot). here is what I have changed out:
DIC, plugs NGK7's,fuel pump insert,fuel pressure regulator, fuel filter, evaporative system purge valve, pcv valve, all vacuum lines (checked and rechecked for proper hook up)
I live in Casper Wyoming~~nearest saab dealer is 200 miles away..and my past expierence with independant mechs here on my past cars have not been pleasant..bought Haynes manual and not ready to give up yet..please help!
