hey honda people

i'm trying to figure out why i'm getting a random mis-fire code 72 and code 74. it's my wifes stock 99 ls integra.
so far i've tryed changing the injectors with no success and i've tryed another dizzy and wires from my project car wich i know are good....... plugs as well and still it keeps popping back up with code 72 and 74... my next guess would be maybe the valves are covered in shit from crap gas ?? i'm not sure wich way to go next any hints on this issue would be great ...... thanks .......

O-yeah and it only pops the CEL for these codes when the engine is at idel - such as when running in the driveway or as your at a stop sign waiting to go
