I checked my psi for fuel pump it was 25 so I replaced the fuel pump filter and strainers car still lopes. Does not lope as bad after changing the fuel pump, fuel filter and strainers but still stalls at stop lights and lopes when going 60 to 65 miles an hour when driving on the highway the power seems like it struggles to stay the speed.
