high rpm hesitation??

[new97v6]

just purchased a 97 camaro with the V6. i noticed when i bought it that if i give it a good amount of gas it hesitates and the service engine light will blink. i know this means misfire but im just curious if maybe it was due to cheap gas that the dealer put in. am i supposed to use super unleaded because when i put that in it seemed to clear it up but the manual says it only needs 87 octane. has this haoppened to anyone else?

plugs, wires, coil packs...


and although this is still up to debate frequently, 87 is the best to use,
