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!

    The EGR valve body was blown off the car 2 times. Codes are miss firing. It happened after the car sat for one week during coldest part of the winter.

    started running roughly and not excellerating properly. Took it to the dealer who cleaned carbon out of engine then ran test and discovered a bad #3 ignition coil. They suggested replacing all three in the back since it involved removing the manifold to get to coil 3 and "no one replaces just one coil. Cost to replace 3 coils $700. cost to replace all six $1100. I've been ripped off by this dealer before for performing work my Tribute did not need so I declined their offer to do the work and am now looking for someone I can trust to fix the problem
