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!
8 valve manual :http://www.amazon.com/Eight-Official-Service-Manual-1981-1988/dp/0837603102 get the appropriate manual for your car and enjoy the Saab!
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.
