Last night the code P1181 came up on my 2001 Saab 9-5. Any suggestions on what could have caused this?

Code means; "Long term fuel trim additive. Max Value, Air/Fuel too Lean."

Sounds like a VACUUM LEAK or related. MAF or O2 could also be "going" bad. Clear the code - check over the engine bay and see if it comes back on.
