hey guys, I recently got a new engine under warranty from Mazda and 100 miles later the CEL turned on -- code 0301 misfire. I brought it back to the dealership to get it checked out and they told me the fix was just a PCM reset due to it needing to relearn the new engine.

Does this sound right to you guys?

btw -- 70k miles 05 shinka; plugs coils n wires changed 2 months ago; maf/iat cleaned few days ago

 

yes
