1987 Honda Accord Fuel Injection system

This is the early version of the "check engine light" to indicate a problem. There is a method to read the problem with a blinking light on the unit. It might be located under the driver seat. Not sure what the process is exactly but there is one you can find to let you put the code. There is then a chart to make sense of the two digit code you get. It sounds though like the engine is in a misfire. I would check the plugs, wires, distributor cap, air filter, etc.
