    i have a mazda 2.0 di 2007 89 kw
    depending on the speed at which the engine loses power at a certain speed, I have to wait for the speed to drop below 1000 and then the engine regains power
    eg in the first if I want to start abruptly, when the number of revolutions goes over 4000, after that the gas no longer receives, then I have to wait for the revolutions to fall below 1000 and then it works normally again, in the second that speed is around 3500 and then the same again .. .

    please help me at least have some guidance on where to start checking

    • Hi buddy and I had such a malfunction as yours I solved it like this, I put it in 6 gear and release the kumplak slowly as if you are going up a hill and hold it so that the pump charges the pressure and leaks over, try 5-6 times if it won't first. I disassembled and assembled almost the entire engine and I did not find a problem that is a malfunction, but in this way I solved it 100% and you will if you try

    i have a mazda 2006, 2.0, 105 KW and my KEY red light is on continuously I own a key card. On diagnostics it shows that the antenna is in the trunk (fault B1131), however all functions are normal for me (central, ignition, lowering and raising windows, etc.). I found out yesterday that when I clear a fault, the light goes off, but as soon as I close the door it lights up again. I wonder if the fault is in the lock and how to solve the problem. No auto electrician knows how to handle it.
    I roll ahead.
