Take it to a real mechanic? Your question is like asking "I can't remember a specific word that I saw in the dictionary, tell me what it is?"
 
pull back the carpet/floor mat in the passenger side footwell to expose the ECU - turn the key on and you should see a flashing red LED on top of the ECU - count the number of times it flashes between pauses and that is the code - could have more than one code
 
he left out one important detail, you have to jump the service connector to get the ecu to blink the code.

google that shit man! I bet you can find a video or pictures or both of how to get the codes from your old rex.

Going to AutoZone is not taking it to a "real mechanic." Not even close. A "real mechanic" should know how to pull the code on an old Honda. It's in practically every service manual ever written for the damn things.
 
d15b1= obd0 ecu. Pull back the carpet on the passenger side. There should be a metal plate bolted to the floor that covers the ecu. Look towards the middle upper area of the plate and there should be a window about the size of a quarter. Turn the key on and observe the led flashes that you can see through said window. There is no need to jumper a obd0 ecu to get codes.

My expectation is you will find a code 16 fuel system error. Code 16 is normally caused by a bad injector that goes out of spec when warm.

If you do end up finding the injectors are bad I would recommend replacing the entire throttle body as a unit if possible. It is much easier than trying to replace just the injectors.

As a side note the b1 and b2 throttle bodies are different bore size so be careful when finding a replacement.
