Question on BMW 3-Series E36 O2_Sensor

Hi. I have a 98 Z3 1.9 that recently hesitates or stutters when tapping the accelerator. Also occasional loss of power. Engines idles fine and accelerates fine accept for that initial stutter not a backfire but like its missing briefly. Plugs are new. Thinking cam sensor or fuel pump beginning to fail, but car runs fine accept for that initial stutter. Z3 has 150K miles and well maintained. No fault codes thrown. Any ideas? Thanks

Could be a coil starting to fail. They usually show up under that initial snap or heavy loads.
