Sounds like your problem is completely different.

Check your MAF...... and clean it lightly with a Q-tip dipped in rubbing alcohol.......

what happens is that maf gets contaminated and will give the computer a wrong reading of the wrong amont of air the engine is sucking in....causing the wrong timing advance and fuel mixture..... causing it to spark knock.... i think that is what you are describing.......if not check your knock sensor..
