Te D4 light is blinking and my car stalls and jumps when driving.
This car has a transmission that has solenoids that control the shifting and sometimes the solenoids or speed sensor causes erratic shifting. The vehicle would have to be tested to see what codes are in the computer and diagnose the failed part from there. I would recommend having a mechanic like, the certified ones at YourMechanic, come and check it out for you to see what is causing the problem.
