ok, first, not every problem will set a code. it is for electronic control or fuel control issues. anyway, there are a few possibilities for this.

1. fuel pump or fuel pump relay. the pressure needs to be checked as well as the voltage at the relay and at the pump as well.

2. ignition control module. common failure for this symptom. shuts off spark momentarily. you can remove the module and take it to a parts store and they can check it for you for free. have them test it 3 times so it heats up.

3. crankshaft position sensor. another common failure.

these need to be tested before confirming failure.

techs today rely way too much on codes telling them failures. old fashion testing needs to be done to actually find the failures.
