anybody know what this could be caused by...
whenever im at full throttle (large load on motor) my car putters, like bau bau bau but its not like a the car has no power bau, its like ah im mean bau, lol. Idk im thinkin knock sensor throwing the timing back (ll.5:1) with 93 and one gallon of 105. Anyone have any ideas?

My thoughts were knock sensor, fuel filter/injectors, cap and rotor.

 

bump

 

no body?

 

I had a similar problem, only mine sounded worse. I thought mine was caused by clogged up fuel filter, turned out to be carbon tracks on my spark plugs. Not sure if that's your problem, but it sounded similar.
