Trouble Ticket Help Requests for DTC P1231
Help Request Posted
2001 Saab 9-5 SE 3.0L Poor Idle Quality, Stall VIN: YS3EF48Z21
Perhaps this is something that some of you Saab techs have seen. These same symptoms on a 2.3 usually mean a bad throttle body, but this is the first 3.0L V6 we've seen with same symptoms. Are throttle bodies a problem like the four cyl. cars?
