Hey, I have a '03 9-5 aero. My newest problem lol is that it surges/ falls on its face when pulling onto the highway. Mostly above 4000rpm sometimes around 3000. I cant really figure this one out but I have already had the common saab problems except sludge (thankyou european Amsoil!) you know DIS TB and CKP.
Any imput is appreciated
Thanks!
Jon

 

just complete loss of power or sputtering?

 

It was studder but when I changed my CKP it went away... wierd? i guess it was ignition
