ok, i dont really know how to explain what is going on with my car...but im gunna do my best...

When i get up passed 3000 rpms my tach needle starts to wave like crazy and then it is like something is slipping and it like bogs down...i dont know what the problem could be...any suggestions??

 

It sounds like a distributor problem, if this doesn't work we can figure it out for you. I am located in Anaheim, CA.
