Hello saabscene, I am new to this community and appreciate all the help I can get. My 2005 saab 9-5 2.3T has just today started idling rough, paired with the p0327 faut code. This happened just after I did a hard accelerating pull in 2nd gear (Unwise to push an older car in that way but what is done is done). I had no engine light before or any trouble with the engine. I am wondering what I should look for in an ettempt to solve this. I would assume it is something mechanical that has gone wrong seeing as it happened after a hard pull almost to redline. Any ideas?
