Mazda3 Engine Issues



  • this has happened to me three times. the only difference is that with mine, the starter does "click" and again when towed to the dealer they have been able to start it without problems.

    The body looks pretty much the same with exception to the front. But, makes me tempted! I want to test drive too. 2.5 liter; at least it makes it .1 better than the new XRS Corolla; can't have a Corolla be faster! Lol. I hope they add on some basic standard features like VSC & a remote trunk release!

    I have a 2008 3s hatchback w/ manual tranmission. Since buying the car in Dec 07 (now have 2800 miles) I have noticed that when the engine is cold during 2 and 3 gear acceleration, the engine acts funny. The best way to describe it is that when I am pressing the gas (say in 3 gear) it accelerate as usual when there is all of the sudden what feels like a bit of a boost in power (almost like when a turbo kicks in). This dissappears when the engine is warmed up. Anyone know why this happens. Is it a problem that may have to be addressed by taking it into the dealership.

    Anyone else experience this kind of issue. Really appreciate any feedback. Thanks.

    I am interested in the Mazda 3 5 door or the new Toyota Matrix with the bigger engine. Does anyone know if the Mazda 3 hatchback has a timing belt or a timing chain and is it an interference engine? I will ask the same questions about the Toyota Matrix.
    Thanks, Rod.

    The Mazda 2.3 has a timing chain.

    I was checking with NAPA on-line and found out my 2009 3 uses an oil filter cartridge. I have never worked with one of these before. Are they easy to change/work with?

    From what I've been able to see online the biggest hassle is getting at the filter to replace the cartridge. I've also read that you have to go to the dealer to get the filter cartridge and parts.

    Here's a link to a page with photos of a guy that shows how he does it on his 2004

    You should be able to buy from any auto parts supplier now, the problem is indeed the getting at the filter, if you are doing it yourself make sure that you do not tighten the screws holding the splash plate in place too much, if you do the nuts in he clips will turn and it will be very difficult to get off next oil change (learned this the hard way, having to blindly reach into the splash panel with one arm whith a wrench and hold the nut while also trying to loosen the screw is not fun). I seem to recall at least one poster cutting a hole in the splash guard under the oil filter (where the hole that is on the splash panel should probably be). Don't let this discourage you it is possible to do.

    I had a similar problem last summer when my PCV went south. My Mazda Protege5 (predecessor to the Mazda3) was basically choking when it was stopped. The solution: install a new PCV (approx. C$350).

    Oops. I meant to say EGR not PCV!

    My 1986.5 Nissan truck is having similar problems. At a stop sign or red light it idles very low and feels like it is going to choke off. The idle is not right, its either too high when very cold or too low when warmed up. Is this the PVC or The EGR??? This truck doesn't have a check engine light so its guess work as to what the problem really is!! I inherited it from my late father and he didn't do much maintenance on it so I'm trying to get it fixed one thing at a time. It only has 71k miles on it and should last a very long time. :shades: :shades:

    Is this the PVC or The EGR

    In my case, it was the EGR, in your case it could be the same or something else. One way of solving this is to get a diagnostic. Consider that the replacement cost for an EGR including labour could be several hundred dollars, you wouldn't want to waste the money replacing it if that did not solve the problem. The check engine light is just a warning signal; a diagnostic pulls up the trouble codes (likely OBD1 codes considering the age of your truck). Good luck!
  • wise1wise1 Posts: 90
    I have a Haynes manual on Nissan trucks that says that the Diag. code will be erased when the truck is cranked 50 times after the code is first given, so the computer will most likely not have anything on it. And OBD1 are not readily available at most garages in this area. :cry: :cry: :sick:

    That is strictly a wrecker resource or some of the bigger swap meets, like Hershey in PA.

    I doubt anyone is reproducing these emblems.

    Now if it were a Mustang, you could order the entire car out of a catalog.

    Also check Hemmings Motor News for Ford Parts providers.

    when I step on the brakes at times the driver side lock clicks as if to lock. I stoppped to get my mail and the other 3 doors unlocked. Then I started car up and the seat belt alarm did'nt go on. While driving down the road I unbelted and the alarm went on.
    Lastly, when parked, if I pump brakes up there is a clicking sound under right side of dash.I've had a rattle in center of dash for two weeks,then these problems stated to occur.
    Do think a wiring harness is loose,or a computer is screwed up? :confuse:

    Code P0128 - Possible faulty ECT Sensor. Where is it and can I replace it, or is it a Dealer issue?
  • I want to put a cold air intake on my 05 mazda3, Put all the intakes I have found mount the air filter down by the left front wheel behind the splash gaurd in the wheel well. I have herd somethings about water getting in to it when driving in the rain. Has anyone had this problem.
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,647
    I'd never recommend mounting a cold air intake down below the level of your engine. It's not just a matter of water getting in--it's a question of driving through a deep puddle, and having a couple of cupfulls of water sucked up into the air intake. When that happens your engine is immediately ruined. There's no warning and no chance of survival. The piston tries to compress the water in the cylinder and bends the connecting rod---instant engine seizure.

    Yes you need a deep puddle and some back luck for this to happen, but it's a real risk.
  • Was that your problem the ECT Sensor? Was it expensive to repair?

    We just purchased a 2004 Mazda 3 and the engine light came on yesterday.

    The code was the same as yours: PO128
    Coolant thermostat condition- low operating temperature

    Probable cause
    low coolant
    open or short circuit condition
    faulty ECT sensor

    Car drives great and shows no problems at all.
