- This video shows you how to replace the spark plugs and coils on a Saab 9-3 (model year 2004). The same procedure applies to model years 2003 through 2011. The engine was rough idling, misfiring and also shaking when trying to increase the rpms. The engine error code read by the OBDII code reader was P1312 indicating a possible spark plug, spark plug coil or the ionization module problem. I replaced the spark plugs and coils which resolved the issue.

You could have used the coils to pull the plugs and used the coil to lightly twist the plugs into place without damaging the threads. Great video btw!
You are awesome!
Thank you!
Whats the module that you said could be the problem? Ive changed my coils and spark plugs and still having problems.
Hello Peter, what's the gap reading on each sparkplug from 1 to 4? Also what's the foot pounds on each sparkplug when tighten them?
20foot pounds and the gap is 35
I tried to do it myself and ended up stripping 2 bolts now I can’t access the spark plugs or coils any ideas or tips? My car is running rough and codes indicate spark plugs and a “b” coil
Use a smaller socket and make sure you take your time
What If there’s a little oil in one of my spark plugs
That likely means that your valve cover gasket is leaking.
yellow coils are bad - it has to be the black as you did . Many got prob because of the yellows
That's good to know. Great feedback. Thank you!
