Question about Honda CRX
If the light on the ECU is not flashing any codes then it is the ECU at fault, either due to an internal fault, or due to a supply voltage or earth fault.
If the light on the ECU is flashing then you need to count the flashes and pauses to formulate a fault code which will then point you in the right direction, but I would say that because you say the car would run okay whilst the PGM FI light was on then it could be the primary O2 sensor at fault.
However, I would look at the light on the ECU before condemning anything.

Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving
