Ok so i was reading one of the posts for troubleshooting and whatnot and i came upon this one "I have this hesitation whenever I accelerate right around 3500-4000 RPM The dreaded 3800 RPM hesitation is cause 90% of the time by poor ground connections between the engine, the battery, and the car. Clean or replace all the under hood ground connections. On 86 model year cars , replacing/regrounding the pressure sensor's ground wire has helped (do not re-ground a 87 or later model year). If there is still a problem after that, look at cleaning the fuel injectors and (on a N/A) that your 5th/6th ports are operating correctly."
I have this hesitation but i don't know what they're talking about with the pressure sensor.... where is it located, or is there another name for it rather than just a pressure sensor?

It's a little black box bolted to the front of the right strut tower. It has a vac line and a 4-pin plug. It has "PRESSURE SENSOR" written on it. It's common name is MAP (manifold absolute pressure) sensor. Mazda incorrectly call it a boost sensor.
