that was your problem right there you took it to a mazda dealership. mazda dealership dont know anything when it comes to rotary engine. they only screw them up. taking things off and not putting it back on right and stuff. you need to get your car serviced at a place that knows rotaries. most likely mazda dealership screwed with something they shouldnt of.
