hi im 17 and just purchased my first mazda rx7. I now own a 87 fc non-turbo and im really excited about getting to work on it. overall the bodys in pretty good shape and the engine only has 70,000 miles on it. It runs and idles really nice but has very poor pickup... i cant seem to figure out the problem even after doing a decent tune-up on the car. My next guess is that it has to do with the exhaust (which is in very poor shape by the way). any suggestions. p.s. sorry if i sound like a nube with this car, its my first rotary and im just learning for myself.
