I'm not sure of the year, it is newer I would say 2000+. When I start the car it requires a little help from the gas pedal to get going, Then idles roughly. Put the trans in Drive and push on the gas and it does not accelerate normally. There is a slight vibration and an audible putt in the exhaust tone. Plugs and wires appear to be in good shape. OBD port throws a #3 cylinder misfire code at me. From my experience this is either a camshaft position sensor or the coil. This is the first Mazda I've ever worked on. Just looking for some input on testing the sensors.

 

could be a few things
timing
firing order is off
bad plug(s)
fuel injector problem

 

bump, please read all

 

Timing i would say
