  • When it happens, does your PRNDL light go out? This happened to me once and it was the ignition switch. And the PRNDL light going out when it randomly happened was the indicator.

Check the electrical connection and grounding of your mass airflow meter. If the electrical connection is loose or corroded, the computer will get the incorrect information about how much air is getting into the engine and will be adding the incorrect amount of fuel, making the car not go very well.

Keep in mind, the mass airflow sensor could also be defective. These are expensive, so you may want to swap it for one from the junkyard just to see if it makes a difference.
