Mazda Tribute Problem
Model Years Affected: 2002, 2003, 2004, 2005, 2006, 2008, 2009, 2010

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.

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!

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.
