I've been reading about the ATF trick all over the web. I think I understand how to do it and what it will do for my car.

Now I want to know if I SHOULD do it.

My car is an 88 RX-7 NA (FC) vert.
Aftermarket air filter is the only real mod. The car runs fine. There is a fair amount of vibration at high RPMs. So, should I do the ATF trick to clean up any carbon build up and stuff or should I just leave it alone. Pros and cons would be helpful too.

Thanks

If your car is running fine there really is no reason to do it. It probably wouldn't hurt but I doubt it will fix the high RPM shake. That might be motor mount problems.

 

Yeah, I thought about it and re-read all the stuff I'd bookmarked about and a nd decided that it would be a waste of time and energy with no positive results at this point.
