i dunno. hard to say looking at it this way... i'm used to a little more information (including how many miles the car has been driven since the occurence). that lets you see if everything happened all at once. like when I threw my car on, I had a DTC for the EGR valve that had me freaked out. Then I checked it against my other code, for a mis-fire, and saw that they happened at the exact same time. Took care of the mis-fire problem (bad wires) and don't anticipate having trouble with an EGR code ever again...
