I have a 2005 9-5 Arc 2.3T. CEL is on after cleaning the injection system and throttle body. Car was running a little rough. At 62k mile, changd the DI Mod. and the plugs. Now at 74K miles.
I cleaned the injection system with 3M injection system cleaning kit.
The car did not run any different. Now the CEL is on.
I took it to Pep Boys for a code reading.
Codes are P0300 Generic Ingnition misfire and P1300 Saab specific code.
Can you tell me what P1300 is?
p1300 is random misfire detected-catalyst damaging
Might you have watery gas? Does it run worse when low on gas? If so fill tank and run a stiff mix of isopropyl alcohol. Red heat.
