Mazda Tribute Problem Report
Mazda Tribute Check Engine Light Due to Engine Misfire
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. - bobhub
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. - Visitor
Check engine light comes on, took the vehicle to the shop Engine misfires. - Visitor
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! - Visitor
engine misfires. first it was the #1, replaced the coil, now it is the #5????? - Visitor
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 both...at 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... - cos2489mo

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? - Visitor
Had the same probleme, when it rained, the engine would misfire. Mazda Tribute for those who don't know, its a hybrid, meaning not pure Mazda. Its a Ford Escape basically. After a while of misfiring when it rained, the EGR valve blew a hole on its side, the DPFE popped off and burned. Brought it to a garage. Had cracks in 4 of 6 coils. Replaced the 6 coils, spark plugs and the head gaskets as it was leaking oil into cylinders. But it didn't stop there, the Mazda Tribute, V6 has 3 catalytic converts. All three were burned out due to the misfire. Had to replace them them all as they were burned out from the misfires. Its was a very VERY expensive repair. It fixed the problem. I own a Mazda 3 Skyactiv. 65,0000 miles, the only thing I've only had done to it its to have the oil changed, never had a single problem with it. I will most definatly buy another Mazda, a REAL Mazda, no Fords disguised as a Mazda. - gus1963
Same issues a lot of you are having the misfire was caused due to leaking valve cover gasket.. the coil paks go down thru the center of valve cover and the seal to keep out the oil was bad so oil leak down into the tube where the spark plugs are and the spark from the coil didn't make to the spark plug (grounding to the block) thus causing the misfire..if you take out the coil pak and see that their is oil on the rubber tubing you have a valve cover leak..hope this helps someone.. - tmaz
Misfire on cylinder 6 - Visitor
#1, Really liked this SUV, 5-spd.
#2, it's NOT fixed, unless I am willing to spend more than the Tune-up & Cat. Conv. replaced now at $1200. It blew a gasket, now #2, #4 cylinders not at 100%. Now I am reading on this site, that the PCM (computer) failed and caused the misfires, that caused the fuel mix out of balance, which threw too much gas into the Cat. which burned it up. Praying for God to guide me on what to do. It's in such great physical conditon, plus a nice DVD/CD stereo installed 2013-:(. - Mazda Tribute 2001 4cyl

My 2004 Mazda tribute sputters/engine light goes on when it rains a lot. Once it dries up , it's fine. - Visitor
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. - Visitor
My baby girl is in the shop... Car didn't want to start or stay turned on. Knocking in engine, engine light turned on... Wheel was shaking and it happened without warning... One minute it was fine the next minute I am broken down. Waiting for the mechanic to fix her but he said that it was the PCM - Visitor
I was driving over water on a bridge during a storm and the ABS locked up and when it came unstuck my SUV shut down while I was going 55 to 50 mph. When I could finally start it again it was miss firing on 4,5 and 2. I changed out all 6 spark plugs hoping it would fix the problem but later that day I ended up taking to a garage and they changed out the ignition coils. The check engine light was still on and showing that 4 was still miss firing, so then the mechanic did an electrical trace and found it was the PCM. When the mechanic looked on Mazada website for service it has a TSB telling how to fix the problem ,you had to change out all 6 ignition coils, PCM and re-flash the PCM. - Visitor
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. - Visitor
