When i put on a new cap nad rotor i noticed that the rotor had about a half inch of play in turnering it. Like it wiggled when i turned it left to right. The same happened when i put the new rotor on.

Could this be a cause of my high rpm miss?

 

No - it should be nice and tight. Maybe the shaft has worked loose from the drive. Matter fact when I reinstall opti's, I usually pull the cap and rotate the rotor "slightly" until the opti pops in. They're much easier to get in this way.

 

Ricehammer, thats what my mechanic did, I had never seen it done like that before.

 

Something is loose or out of alignment here.

 

Do i need a new opti or do u think its fixable?

 

I think you need to closely examine the parts to determine what is the exact problem. Look for indexing posts broken off, missing fasteners, loose parts etc.
