    MP3 ECU Find

    I got my MP3 ECU from car-part.com. Worth it for me, but you may have to run higher-octane gas to avoid pinging.

    2003 Protege5 FSZE Engine swap issues and options?

    I guess one question I'd have is whether high-octane gas actually fixes the pinging. If it does, then that's as sure a sign as I know that it needs higher-octane gas. As I mentioned above, the three octane levels common in Dallas are 87, 89, and 93 (91 is not commonly available afaik). 89 and...

    2017~2025 Need Part Numbers for CX-5 Right Rear Wheel Arch Clips

    I bought the part from my local Mazda dealer, and it came with all the blue and green clips. It didn't come with the rear-most black, plastic rivet, or the one-inch black plastic "'clip" that snaps in place near the top of the arch. Luckily, I was able to harvest both from the vehicle (my...

    2003 Protege5 FSZE Engine swap issues and options?

    I got a JDM FSDE replacement engine in my P5. I noticed pinging with 87 octane, especially if I accelerated going up a hill. It's $.30 extra to get 89 octane and another $.30 to get 93 octane here in Dallas. I can pay for the 93 octane because I don't drive much (I work from home and ride my...

    Mazda FS-ZE engine idle issue

    Ugh.. At this point, many of us have had our accordion intake hose crack on the bottom allowing unmetered air into the intake. Mine cracked years ago; done by an oil change place when they were checking my air filter to up-sell me. They also broke the handle off the oil dipstick and...

    Time to sell the MP5 - Thank you so much for everything

    Does an impact wrench help with rusty bolts, or do they just sheer the bolt off? I have zero experience with rust (knock wood).

    Best aftermarket Protege5 axles?

    I am also interested in hearing about good axle replacements as I've got some clicks. OEM would be expensive, and I don't know that they're still available for purchase (I think the local dealer said they were not last time I checked). From what I've heard, Cardone refurbs are not good.

    2002 Protege5 Instrument Cluster warning lights

    IIRC, the cluster has two multi-pin connectors. I wonder if the missing warning lights are all in *one* of the two connectors. Maybe you can plug in the connectors and wiggle them a bit and see if any lights come on?

    Passenger side ebrake clevis sticks on (Protege5)

    If you can't fix it, maybe just don't use the brake. I put my manual transmission P5 in 1st or 2nd gear when I park it and I don't set the brake. I learned as a kid that this was a valid option and I've never had a problem in 21 years. If you've got an automatic, you can put it in Park, of...

    Sources for MSP ECU? 2002 Protege5

    As a general statement about car-part.com, I had a good experience with my one purchase from a car-part.com-affiliated seller, but I had to be careful. For example, I would see a listing for an MP3 ECU and the vehicle pictured was just a regular Protege - and most listings do not even have pics...

    Mazda FS-ZE engine idle issue

    I hope it's not every 10,000 kilometers. That would be extreme! :D My JDM engine has the same sticker.

    Sources for Protege5 Roof rack delete strips?

    Would a salvage yard be a good option for you? Most P5s I see in my local yards have the original roof rack, but I think later models (2003.5 or Canadian models or something?) may have come with the filler strips. Even if they didn't come that way from the factory, you may find a car that had...

    What have you done to your P5 today?

    That's fantastic news. :) Not really related, but you made me think of this... Way back at 30k miles, I got my manual transmission fluid replaced *at the dealer*. Car immediately had intermittent trouble shifting, most noticeably from 1st to 2nd. I turned the car around and went back to the...

    Sources for MSP ECU? 2002 Protege5

    I got my MP3 ECU from car-part.com. The seller even sent me a pic of it before I bought it. You may be able to find an MSP ECU there.

    What have you done to your P5 today?

    I've had good luck by replacing three of my four mounts so far with OEM ones, but they were spendy. While I drive spiritedly, I don't shift anywhere near aggressively, so maybe my needs are less.

    Protege5 Dilemma

    I was wondering about that radiator as well. Definitely keep an eye for leaking coolant on the ground and the level of coolant in your translucent coolant overflow/reserve tank. Hopefully your hood latch is still secure enough that it won't fly up on you at highway speeds. I just replaced my...

    To part-out or not to part-out?

    That certainly sounds scary, if the wheels "shifting" during a turn is definitely due to rust where the suspension mounts (and can't be explained by rotten bushings or loose fasteners). If you're looking for advice on whether you should try to fix it, you might get more feedback here if you can...

    Protege5 Auto vs. Manual passenger side axle…Different?

    Based on what Rock Auto shows (or doesn't show), I'm going to say that the passenger-side axles are the same for auto and manual. If you want to be sure, find the parts catalog PDF for our cars and compare the part numbers. Or it may be easier to visit one of the online Mazda dealers and look...

    What have you done to your P5 today?

    I just replaced the four bulbs in the instrument cluster. I'm embarrassed to say that they've been more than half burned out for ten years or so, but I didn't know they were so easy to replace. Bulb sizes I used were 194 and 2723. I reused the little orange slip covers that were on the...
