2006 saab 9-5 stn wgn onboard diagnostics code P1181 and P1300

SOURCE: saab turbo 9-3 need computer trouble code

P1300 is random misfiring. I suggest replacing your DI cassette with a known good unit or a replacement unit. Give more info on your vehicle. Any symptoms or running rough?

SOURCE: Hello, Saab 2001 93 with trouble code P1181.

P1181 says Long term fuel Trim Additive, Max value, Air/Fuel too Lean

Check for vacuum leaks, check mass air flow sensor if this is ok - check fuel supply (pump, pressure)

SOURCE: p1181 diagnostic code

P 1181 code- long fuel trim max value air fuel lean.possible causes fuel filter clogged or restricted-fuel injectors dirty or restricted-fuel level too low during heavy acceleration events- fuel pressure regulator has failed.not supplying enough fuel- water or alcohol in fuel causing low 02 sensor signal during acceleration.

SOURCE: I have a Saab 2006 9 3. The shift knob falls off.

I own a 2006 9-3 Aero convertible and decided to replace the automatic shifter trim/boot. It's the part that shows the gear selections (P, R, N, D, & M). It required that I remove the shifter knob. First, slightly twist/turn and pull (perhaps wiggle is more accurate) down the shifter collar just below the knob. One to 1.5 inches should work. The ring inside the collar is what secures/tightens the clips of the shift knob against the shifter mechanism. Pull straight up on the knob. Done!

Don't know if it is any help but I had the same problem and it turned out to be the intercooler hose was split and sucking air. Fixed it and know problem now.
