Sputter problems

[ineedacar27]

I just got a 90 TSI AWD so i don't know that much about it. when i first go the car i didn't think about it and just put 89 gas in it...that's what i used to put in my old car. so needless to say, it didn't run too good. now that i have emptied that gas out and put 93 in...it still sputters pretty bad when i start to boost. i know that it has the MAF in it so that was my first guess. Is it possible that I have messed up the plugs and wires? or might there be a leak in one of the i/c couplers? please give me some help even if you just have a slight idea, it will be appreciated. im not familiar with these cars at all, but im workin on it

thank you

could be lots of things.

try new plugs/wires

after that, it could be anything. ignition coil pack? who knows.
