The first thing I did was to give it a good service changing all oils, plugs and filters. Regarding your car which with that mileage is a "young" car, and basically all engines are the same when it comes to the basics such as ignition etc. The only thing to watch with a Saab engine is that it is the "wrong" way round in the engine bay!, Note the plug numbers on the engine! If it cranks over easily, but doesn't fire I would suggest the following: Check that the plug leads and the plugs are good, Crank it over and take a plug out. If it's "wet" ie smells of petrol then the problem lies in the ignition side. Check the distributor cap is not cracked/ dirty inside. Clean/check all connections from the coil and distributor. You can check if you are getting a spark by taking all the plugs out, connecting one up to a lead and holding the plug against the engine while somebody cranks the engine - be careful don't electocute yourself. If there is a spark then it's a fuel problem, replace the filter check there is fuel pumped while the engine is cranked. Yeap a clutch will be dodgy if left for along time, but may get better with use. However if the car was used mainly in town then it's seen a hard life and may require changing, this is suggested by the crunching reverse. It is actually quite easy to change in the car. The Haynes manual is good for this - you should be able to get one through a good auto store. If a garage says the engine has to come out to change it, walk away as they don't know what they are doing! I have changed two saab clutches myself now and it takes about 3 hours with simple tools As stated follow the Haynes manual. A Clutch kit consisting of the plate and the pressure plate is about 80 here, but I suspect you will get one in the USA for about the same cost in dollars, again an auto parts store job. Crunchy reverse can also be caused by the lack of an oil change or the wrong oil in the gearbox the box uses engine oil eg 10/30w NOT Hypod gear oil such as ep80 etc. A weak fan can be simply that the hoses to the de-mist vents need putting back on! To change the fan motor is a pain as the whole dash has to come out however check that the air filter in the heater inlet! This often gets overlooked and could be jammed with leaves dirt etc. Changing it will make a big difference. Just open the bonnet (hood) and look at the filter. Switches get sticky with age, Scrap yards are the best way to deal with that one. They are expensive from the dealer here in Scotland. As to a dealer in Rhode Island it's just alittle bit too far away for me to know! Good luck, Keep us posted Malcolm Stonehaven, Scotland. Sent via Deja.com http://www.deja.com/ Before you buy.
