change the fuel filter as it may be blocked and get the rail fuel pressure checked as well.

Try cleaning the throttle body and iac motor. Verify there are no vacuum leaks

I've doe all that when I replaced a bad coil. Could it be the electronic gas pedal? this only happens at low rpms.or a throttle position sensor?
