Both Auto Zone and Advance Auto carry the plugs you need for your Saab....you can check on-line for the store nearest you...if they don't have them in stock they can order them for you and you can usually get them the same day. I have never had a problem ordering plugs for my 1997 Saab 900S nor for the 1997 Saab 9000 and 1999 Saab 900SE that I work on for friends.....hope this helps.

I have a 96' Saab Turbo SE Convertible. My code is 3146. Try it to see if it works.

You need to change all of your wires, there may be one or two of them gone bad. "Check it at nite to see wich one is sparking fire from the wires"..

yes it is the ignition coils . po304 is a miss fire on #4 cylinder.wires and plugs should fix the problem unless ignition coil is not firing. there are 2 coils they run 1&4 2 &3 cylinders.

I'm afraid if you don't have the code, you will have to take it to a local dealer or specialist radio store to have it re-coded.

Fortunately, it's not expensive.

you should check your fuel pressure and be sure it is within spec, is this a 2.0T or a 2.3 non turbo and also this is fuel injected correct? same as the U.S.A. 97 saab 900s? if it is a 2.0 with direct ignition try changing out the DI cassette with a friend or junkyard unit to see if that solves it -Jeff also please rate

woooooo, wait a min don't take off the gear box befor confimimg my question as you might not have to take the gearbox out.is your gearbox at the front of the car ahead of the engine? if it is i can walk you through it without taking the gearbox off, this is standard
