I have heard both good and bad about the box, but what are the symptoms of one that is going bad, or is bad? I think ive gotten though just about every potental issue with my car starts to run like crap after a while (even after replacing a fuel pump shaft that was more then a 1/4" too short).
Is it just they work or don't and if the car runs its fine, or is there more to it, say run ok at ambient temp but bad at temp, cut and out, etc....?
