First off, what the heck is a DIM? Do you mean Distributorless Ignition System Module (commonly referred to as a DIS Module)? Second you just said it has been "letting go". Can you be a little more specific there. How, what are the conditions, what exactly is the car doing, how do you know it is "letting go"? Third, there are a lot of questions that don't go answered because either nobody knows the answer or it has been asked 1000 times before and there is a post about it just two posts down. I believe your question would fall under the former set of circumstances. Apparently, myself included, nobody knows what a DIM is. And fourth, just because your question does not get answered right away is no reason to complain or act like the unfortunate son. 99.99% of the time if someone has an answer or even an idea they will post it.
