I was wandering if someone could help with my fueling problem.
The car recently had a major service plus new HT Leads, Plugs, Dizzy cap and Rotor Arm. Since then it seems to the exhaust smoke is very blue, but still runs smoothly untill I accelerate hard and it start to miss and back fire.
Is there a major problem or is it a case of replacing a changed componant from the service.
This problem was not there before the service.
Thanks for your time.

The fuel pump is in the top of the gas tank, accessible from the trunk, under the carpeted floor. here is a link to a good FAQ answer about fuel pumps, follow the pricing link for info on replacing just the insert, which is cheaper than replacing the entire pump. Carry out the checks described to ensure that it is actually the pump causing your problem!
Here is a link to one of the best Saab info sites - it might be more reading, but has the best information!

Has info on just about every thing, including shifter. You didn't say whether yours is manual or auto. You could source a used shifter from your local Saab specialist or local junk yard, though there aren't too many Saabs at the wreckers; a good sign!
If the car's a standard, it'll more than likely be the shifter linkage. Saab's linkage involves a lot of plastic that will crack and wear over time. A reputable European car repair service should be able to get the parts and fix the linkage. It's not cheap.
If you are on your original fuel pump, be advised that they are known to last, on average, about 100,000 miles. Another common fault, besides that and the direct ignition cassette you have already mentioned, is the crankshaft position sensor. The prelude to total failure of this component may prevent starting or cause stalling and rough running. The ECU needs the signal from this sensor to know when to signal the DIC to fire a particular plug.
Fault codes come from the fuel injection system diagnostic circuitry, which can store up to three faults. They can be read through the check engine light in the dash. You'll need to make a switched test lead with a spade connector on one end for connecting to the test connector. The other end is connected to ground. In 1992 the test connector is located beneath rear seat in sedan, or under the bellows ahead of shifter in convertible. With ignition off and test lead off, connect test lead to ground and test connector pin 2. turn ignition key to ON When Check Engine light comes on, turn test lead switch ON; Check Engine light should immediately go out When Check Engine light flashes ONCE, IMMEDIATELY turn test lead switch OFF Any fault codes will flash through the Check Engine light, with a long flash at beginning and end of each code; code flashes are short flashes, each block of flashes is separated by a longer space. With the engne OFF, the first fault code is that for "No RPM" 1 2 2 3 1, it will look like oooo x xx xx xxx x oooo where o = steady on, x = single flash There are over 20 fault codes, so get yourself a copy of the best source of info on this car: the "Bentley Bible" aka the Saab 900 Official Service Manual, costs about $40 from Amazon 16 valve manual: http://www.amazon.com/Saab-900-Valve-Service-Manual/dp/0837603137 8 valve manual :http://www.amazon.com/Eight-Official-Service-Manual-1981-1988/dp/0837603102 Hope this helps, if it does please give a "thumbs up", thanks Saabreur
