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!

    Bought my Tribute brand new in July, 2002. I've maintained it very well over the years and never had any problems with it. Recently, I noticed that whenever it rains or the humidity is high, the car idles rough and stalls out when I'm driving. I brought it to my mechanic who advised me it was my catalytic converters and suggested to replace a big price. He conveyed to me it was the result of using 87 octane gas and should use only 93. Well, the car ran fine for a week and then the same rough idling happened again. This time when I tried to drive it to the mechanics shop, the engine just died and I had to get it towed. Once again at the shop and while the weather was without humidity or one drop of rain, it ran fine. Quess what? the same thing happened again and this time when I try to start,it won't exceed 6000 rpm when I rev it up...

    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?
