Replying to: bostondaphne (Sep 24, 2008 8:32 am) Hi, I suppose I had a moment of hope. False hope that is. The car still runs terribly. I had a former Saab tech look at it last week and he thinks I need a new Direct Ignition Cassette. Can't afford it right now, but he thinks that should do it. Another tech--non-Saab thinks I need to get the fuel pressure checked before doing anything... Please let me know if you have any success with yours. -Mark
#6 of 9 HELP! '99 Saab 9-3 by bluedogs Sep 24, 2008 (11:26 pm)
Must crank at least 5 or 6 times before it finally and roughly starts. Slow, bogged take-offs. Nearly constant surges when idling. But when going down the road it will fly! It is really fast and runs great when driving. I've had several techs look at it and put a computer to it. MAP sensor is good; all hoses seem to be fitted properly; both O2 sensors replaced; new plugs... One tech thinks I may need a new Direct Ignition Cassette. I've heard that those can go instantly? But he claime they can slowly decline? Any help is greatly appreciated, as I'm about to get full, low deductible insurance and burn the thing!!!
#7 of 9 98 Saab Convertible - Running Extremely Hot by olearymag Oct 03, 2008 (2:40 pm)
My 98 Saab is running extremely hot, just replaced radiator and still running extremely hot, the old radiator was singed (white) at the bottom of the radiator, the head gasket was deemed OK, thermostat opens OK. temperature gauge reads normal temperature. Any suggestions appreciated.    olearymag Replies to this message: olearymag (Oct 06, 2008 4:45 am)

I had a similar problem to yours on my '99 93.Check the vacum hose near the air filter it connects to a small plastic cylinder that opens and closes it's smaller than a golf ball and looks a bit like a funnel.Sometimes it sends a message to the computer if it does'nt work but in my case it didn't.I changed it and my car got back to normal.My specialist had a few clients that had the same problem.Give it a shot,the part is not expensive!
