    Sometimes when I want to go and hit the gas it takes a minute to kick in; then I take off alot faster than I intended to.

    My car stalled as I was approaching a stoplight at about 10 mph. I had just started to accelerate through the light when my dashboard lights came on, the engine stalled, and my power steering and brakes went out. The car started right up again. I went to a Mazda dealership in Ft. Wayne, IN, who could find nothing wrong when scanning the computer. I drove to Michigan and back to Ohio, with no more occurrences. I had the car checked again by my Mazda dealership in Beavercreek, OH. They couldn't find a problem, either. This has just happened the one time, so far. I will update this after checking out this update.

    My car is slow to accelerate when I try to take off and when I do it takes forever to accelerate then when it surpasses 4,000 rpm it makes my transmission jerk and then it takes off

    Not all the time but getting more intense with the summer heat that when we stop at a light the car will try to stall and start shaking, I have to rev the engine to get it to stop doing it

    My engine seems to get bogged down on takeoffs. I thought changing the spark plugs would help, but to no avail. This is most likely the issue.

    Upon acceleration the car would hesitate. I took it to get fixed and they stated it was ignition coil and needed a tune up. It did seem to fix the problem, however they also mentioned that it came back with a code to replace the knock sensor.

    Car started stalling and jerking between 30-40 mph and died out while driving. After long trips there is a white smoke coming out from front passenger tire.

    While turning corners, distinct acceleration lag, for a few seconds, it never dies, just lags, then kicks in

    When I start up the car the computer system goes crazy. Then the check engine light will flash off and on consently. The car is hard to steer and it feels like it's gonna stall out I try to accelerate but hits hard to drive..

    My car has been having issues at startup and then initially not wanting to accelerate. It lightly jerks like its not getting steady gas flow. Took it to a friends shop and he could get it started by banging on the gastank under the car. He replaced my fuel pump for me but its still having issues. My check engine light didn't come on until after the new fuel pump. Read the codes: P-2177(Fuel system too lean at off idle) and 2187( Fuel system too lean at idle) he said it may be the fuel injectors but reading through the manual it looks like the PCM is the culprit.

    Después de encendido 45 minutos después empieza con inestabilidad de rilaten y en el scaner el código es P0300
