My mazdaspeed protege hesitates quite a bit when i get into high rpms. anybody else? anybody know why/or know how to fix?

 

to cause hesitation your engine would have to not be receiving enough airflow,spark, or gas. the first things to die off are the spark plugs, spark plug wires, and coil packs. if it were me id start with plugs, then wires, then coil packs. all of which are relatively cheap and require very little skill to replace
