Suggest you go to www.saabclub.org/ - the owners' club can answer all these questions and point you to reliable workshops and help with buying/selling parts and cars - Saab owners are particularly keen e.g. I have 2 SAABs in the USA and 3 in the UK Good Luck! N.B. the firing order is 1-3-4-2 but without the proper workshop manual I won't say any more! You want the Bentley 16-valve manual; see http://www.bentleypublishers.com/saab/index.htm

mixed spark plug wires
The cap and rotor would not be the problem as they are installed in preset position. Therefore the problem lies in one of two other possibilites: (1) SPARK PLUGS: Did you check the gap on the spark plugs? New spark plugs do not always come pre-gapped and it is always a good idea to check them. Spark plugs that are not gapped correctly will "miss" or "skip" and not give good performance. (2) WIRING: When you changed the plug wires, did you ensure you bought the right wires for your application? If the wires are not the right ones, you will get a "miss" or a "skip". Another problem would be the routing of the wires from the plug to the distributor. Did you remove all wires at once and maybe crossed up the order that they fit back on the distributor? Are the wires fit snuggly on the spark plug and the distributor cap?
