Check Engine S80 1999

I have a 99 Volvo s80. The check engine light keeps coming on. I was unaware to use 91 Octane gasoline when I bought the car. I had filled it three times with 87 Octane. The dealer where I bought the car keeps telling me its because it had 87 octane in it. Now I had used 93, and the light was reset and came on again yesterday. He said the car has to get use to the higher octane again and thats why the check engine light comes on. He said the code that comes up is P1330 MFR Controlled Ignition System or MissFire. Is this code for anything else that could be wrong with my car? My warranty is up soon and I don't want to have to pay for it. Please help!!!!!! Would the 87 octane and now the switch to 91 or better make this code come up? My brother in law is a mechanic and said something about the oxygen sensor. Could this be it?

    i would go to another dealer. your missfire is probably do to faulty ingition coils. running 87 octane will do nothing to hurt your car other then performance. unless ofcoarse you continued to run it and/or drive it hard then detonation could be an issue.

    Obviously not a Volvo dealer! The regular gas will not cause a misfire, it will retard the spark to prevent knocking and your gas milage will suffer a little bit.
    A Volvo scan tool will pinpoint the troubled area. Probably a bum coil over the spark plug, but you first need to know which plug is misfiring.
