You may need to remove the ignition housing assembly to find out whats wrong inside. There are a series of small gears which connect the ignition barrel to the ignition switch & also operate the reverse gear lock mechanism. You'll need a special 3 pronged tool to remove the assembly - available from SAAB dealers.

while engine running and warm, try spraying carb cleaner onto back engine at where injectors go in. if idle go up, then replace inj. seats.
takes a $12 tool from Snap-on to pull inj.'s (which you can make very easily if you're of the mind from scrap angle iron) and a 12mm hex for the seats. be careful as they will be VERY brittle!

Have you had your mass air meter checked or replaced? This is the unit attached to the air intake hose behind your air filter. It senses the air temperature, speed, density, etc... and adjusts the fuel/air ratio to keep the vehicle running at "peak" performance. Also, check your TPS (throttle positioning sensor) it can also cause the problem you speak of. The TPS adjusts your engine speed/idle etc. and also compensates for hot/cold changes etc. This is roughly a $35.00 part and in most cases usually an easy fix.

Sounds like you're running rich.
First, change the air filter, and check that the air intake isn't blocked somewhere.
If that doesn't sort it out, it's the carb. They have an automatic choke (cold start), which could be sticking on and causing problems.
One thing it isn't is the timing belt (sorry Satanscash) as this engine doesn't have one... and even if it did, failure of the belt results in a very dead engine!

If you have excessive white smoke coming from the vehicles exhaust, it sounds like your headgasket is failing. Especially having a rough idle too. Check your coolant level, does your exhaust smoke smell sweet, like Antifreeze? If so, the gasket has blown. Hope this helps...
