Have you burped fuel rail after changing filter? Could be some air in the line. Checked for spark? And have you checked timing?
I had the same problem before the fuel pump and filter change has good spark and I will check my timing. Changed pump 2 months back didnt have problem for about a day really became a problem when it started frosting at night. It stalls and stuffers here and there during acceleration and wont stay running for more than 5 min will idling
The motor is acting like its choking or starving for air or fuel k&n cone air filter is on It
I checked for spark today when I changed my plugs all good spark
What's your fuel pressure? Any vacuum lines disconnected? Try cleaning the idle air control valve and mass airflow sensor
Be careful with the mass airflow sensor, it has delicate parts
I sprayed carb cleaner on all my vacuum line checking for leak I found nothing
I know it mass air flow sensor is bad but its been like that for 4 year never made a difference
