My daughters car 189000 miles 3800 motor. Stalling issues, had fuel pump replaced mechanic found pump screen had fallin off. This solved stalling issue. However, car still shudders for lack of a better term. Seem to have a fuel or spark issue. Maybe plugged injectors? Car run well at first but starts showing symptoms after a few moments intermittantly however Thanks in advance

Whenever those symptoms appear on this engine, the first things to look at are the plugs and plug wires. Once you know they have been changed recently, then you can look at possible bad coil or plugged up injectors.
