Asked by cutlass70 Apr 22, 2013 at 07:59 PM about the Saab 9-5

Question type: Maintenance & Repair

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?

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.
