Hi chavito,

An error has been detected by the PCM and is indicating by the blinking D4 light.

Get a free scan done at Autozone and let me know the EXACT trouble code.

P0135 = HO2S ( Heated Oxygen Sensor ) heater circuit malfunction.

P0758 = Shift Control Solenoid Valve " B".

Test would have to be performed to verify the source, could be a faulty sensor/solenoid. Check if any of the wireharness are loose or contaminated.

When did the Check Engine Light started showing?
It is a separate issue with the D light blinking.
