Narrative:
Localizer was tuned and front course set at altitude during approach brief for ILS runway 4R ewr. Normal company practice is to de-tune frequency until arrival phase to 'clean' localizer and GS scales off eadi. ATC kept us high and fast, then tried to slow and descend us at some time (B757 doesn't do this), then told us to stop descent until slowed. ILS frequency was not reselected, but FMC never gave us 'runway/ILS frequency error' message like it should have either. I saw localizer course on map and began turn on heading select, but still flew slightly through. Then I looked down and selected ILS frequency again. Wouldn't have happened if FMC had given us message and ATC hadn't created high workload. Also, it is a bad practice to de-tune ILS after approach briefing.

Title: A B757-200 FO FAILS TO RETUNE HIS ILS RWY 4R FREQ AND OVERSHOOTS THE ILS LOC COURSE 12 MI SW OF EWR, NJ.
Narrative: LOC WAS TUNED AND FRONT COURSE SET AT ALT DURING APCH BRIEF FOR ILS RWY 4R EWR. NORMAL COMPANY PRACTICE IS TO DE-TUNE FREQ UNTIL ARR PHASE TO 'CLEAN' LOC AND GS SCALES OFF EADI. ATC KEPT US HIGH AND FAST, THEN TRIED TO SLOW AND DSND US AT SOME TIME (B757 DOESN'T DO THIS), THEN TOLD US TO STOP DSCNT UNTIL SLOWED. ILS FREQ WAS NOT RESELECTED, BUT FMC NEVER GAVE US 'RWY/ILS FREQ ERROR' MESSAGE LIKE IT SHOULD HAVE EITHER. I SAW LOC COURSE ON MAP AND BEGAN TURN ON HDG SELECT, BUT STILL FLEW SLIGHTLY THROUGH. THEN I LOOKED DOWN AND SELECTED ILS FREQ AGAIN. WOULDN'T HAVE HAPPENED IF FMC HAD GIVEN US MESSAGE AND ATC HADN'T CREATED HIGH WORKLOAD. ALSO, IT IS A BAD PRACTICE TO DE-TUNE ILS AFTER APCH BRIEFING.
