I have a 2003 Cadillac Escalade EXT with only 34k miles on it. As soon as I bought it I put 93 octane in it and came up with multiple codes. Including Fuel too rich and MAF. Does this mean have to replace parts? AutoZone told me that if I put 87 that the Engine light may go off. I only filled it with 93 octane 1 time. Please help!

The fuel you used is okay to put in and use, There several area that should be check and that would be the airfilter, replace if plugged, If you have a MAF sensor code that should be resolved the MAF sensor measure the amount of air entering the engine, You may just need a MAF sensor.
