was told by a mechanic that the "pdi computer kit" needs to be replace. never heard of it.

 

sooo do you need help finding a new mechanic? Ive never heard of it either. Ask him what it is/does try to find out some more info. Could be a different name for something you have heard of, or its just something we dont know about. Or hes an idiot. But talk to him first, im sure he knows more than us.
