We have a 2005 Saab 9-5 Arc sedan with 100K miles on it. It's my wife's daily driver.

A few days ago she said the engine was running rough and wants to die after putting the transmission in gear. She also said the engine light on the dash is on (continuously on – not flashing).

This morning I went out to her car and plugged in my OBD II scanner. There was one error code:

Manufacturer Control P1230 $11

Any ideas what this means? Is it the throttle body perchance?

Thanks
