Verified

If the engine is misfiring, it may be caused by a damaged wire(s) which connect the fuel injectors to the Powertrain Control Module (PCM). The damaged wire(s) can be repaired or the emission wire harness replaced. A misfire can result in a loss of engine performance and illumination of the Check Engine Light.

    Just got word from the dealer, after 3 days of diagnostics, that it needed everything after the new pcm was installed, new manifolds, catalitic converter, and who knows what next, after reading the other stories here, I decided to just dispose of it, and cut my losses, I WILL NEVER BUY A MAZDA EVER AGAIN and will tell anyone who would ask to never buy a Mazda.

    Already had coil replaced for misfiring and damage at #3. Now the misfiring/hesitation is starting again. Talked to Mazda and they "never heard of any such problems". With only 69000 miles and no other problems I hate to replace the vehicle but reading other posts with same issue it seems to be my only recourses.

    Bad PCM from misfires on 5&6 caused burn-out of catalytic convertors on manifolds and $2,500.00 repair. Diagnostic showed bad coils on 5 & 6, but after replacement, problem remained, hence PCM replacement, but only after catalytic convertors were damaged. This severely affected engine performance!

    Blocked exhaust. Blown EGR valve. Rough idle. Decreased mileage. Mazda dealer has fixed everything but the problem. Problem persists from 2012 to 2014 without resolution. Repairs cost more than vehicle's market value. Would you buy another Mazda?

    My car rough idled and stalled... towed to the shop and was told it's a known PCM issue with this vehicle. We had already spent ~$500 replacing two coils due to misfires. We'll see what happens when it gets to the dealer. I love my Mazda and hope it's not time to replace her.
