Help! Car Idles Rough, Won't Accelerate, Service Engine Soon Light Flashes, Code P300

And ordered MAF cleaner.

The codes were reset and am waiting for what happens next.

Do you have any input?
Check the ground by the ECU inside the car. Given the "B" codes, you might have some corrosion around the ground connection.
