I got a “check engine” light on in my 2002 Isuzu Trooper after I had the timing belt, spark plugs fuel filter and fan belt replaced. It has been checked by several mechanics, and the codes that the scanner shows are : 1311 and 1312. It seems that there's no information in the scanners that they have (Snap on), and or the software doesn’t have it. So far I can't find information about the codes, it seems that it may be that the coils or the injectors are failing (missfire). Please let me know if you have information about these codes, so I can fix the "check engine" light.
