the fan staying on really has to be either the fan switch or a faulty relay, the stuttering under acceleration could be either fuel starvation or possibly a DI fault, my car had a similar rough running problem that was the DI on my 94 Aero, but renew the spark plugs first, they cost a lot less! also you should check the coolant temperature gauge by grounding the sender wire at the block and checking that the gauge does go to the top, your gauge could be reading low, I've seen this too, check it now, before you need another head gasket Liam UK "Huw" <hflj1nopsam.ac.uk> wrote in message news:3BE26BC8.657F666Fnopsam.ac.uk... > Could be a fuel starvation problem. > > > As for replacing the Alternator because the fan stayed on all day that > surely is the fan switch, when the engine is not running the alternator > is not turning. > > Huw > UK > > Joseph Hoh wrote: > > > > I am not very savvy when it comes to cars, but I will try to include > > as much information as I believe is pertinent. > > > > I have a '97 Saab Aero 2.3L Turbo Automatic with 82,000 miles. > > > > Issue (about 2 weeks old): > > When cruising in 3rd or 4th gear (40-60 mph), and I punch the gas, the > > turbo indicator goes just into the yellow/red alternating area (never > > above), and the vehicle stutters briefly, but continuously.
