I'd check #1 spark plug.
Usually a misfire code "fix" is a spark plug, spark plug wire, or a coil pack / distributor.
Keeping it simple...I'd go with the spark plug first and then look at the condition of the wires.
Back, from LEFT to RIGHT: 1-2-3
Front, from LEFT to RIGHT: 4-5-6
I really hope your bad coil is in the front (4-5-6).
Rear ones are not funt o get to. Not impossible, but a pain. My No.3 went out this Summer, so I know. I changed all three coils in the back, and refreshed ALL plugs.
Hi, this car doesn't have just one coil, it has a separate coil for each spark plug so u have six coils, the coil is plugged right onto the top of the plug in a deep well this is called a "coil over" ignition system, see picture of coil below Thanks

I'm not sure on your specific model, but most automatic transmissions do not have a drain plug. You need to remove the entire bottom pan to drain the fluid.
Best method is to loosen/remove all bolts except two corner bolts, then when the pan comes loose the fluid will run from one side -- hopefully from one corner. It's always a little messy, even for experienced mechanics. Have a new gasket ready and a filter kit (you need to remove the pan to get to the filter).
I can almost guarantee its the ignition coils. Its common with the 2004 mazda mpv. They are very expensive but I just changed my #3 coil and boy im I glad I did that. With the Mazada mpv 2004 hopefully a check engine light will come on so you can see which ignition coil it is. Once you find out change it and the spark plug that goes under it. If its one of the back ignition coils its gonna be expensive or time comsuming. I would change all three coils in the back and all three Spark plugs so that you dont have to worry about them again since you have to open the manifold just to get to them. I recomend taking it to a auto shop that you trust. While your back their you can change the pvc valve and bromet I think its called (the cushion for the pvc valve). Its all in the same area. The ignition coil could run from about 45 dollars each to about 65 depending on where you go. One more thing, if the check engine light comes on you have to check it quick because it cancells it self out if the ignition coild is not that bad yet. the sometimes it stalls and sometimes it doesnt syndrome. you take it to the shop and it doesnt happen again until your home thing lol. Thats just the beggining of it going bad.
After I changed my Iginition coil and all three spark plugs in the back of the engine the car runs like a race horce. no more stalling. im very happy I did that. It cost me about 125 for the coil and the three spark plugs and a new thermometer for another issue. and about 200 bucks to put them in, I think I got a good deal considering most dealers in nyc charge 100 bucks an hour to work on your car. Its not that big a deal of the work. You just have to know what your doing. It took him about 5 hours to complete the job. I hope this was helpful.
pull one plug at a time and put the wire on it. set it off to the side and have someone turn the car over. if the plug sparks its good. of not its bad. my suggestion is replace all plugs. maybe 20$ worth of parts.
chances are fairly good it's the coils - I've posted about this on Edmunds. the OEM design is truely idiotic & has a vent that allows moisture down into the plug well - that shorts the spark & causes misfires. On our 2004 MPV I got away w/cleaning & drying them extremely carefully then sealing the vent w/silicone as a temp measure, then ordered perfect replacement after-market coils off ebay that sealed the wells & stopped the problem -and- were a tiny fraction of the OEM price. good luck, BK
