the old PGM-FI thing - i have 87 honda prelude

My car has the good ol' PGM-FI dash light on problem. This seems to bea common problem and I have seen a variety of explanations.The light normally comes on when you turn the ignition key andimmediately turns off after I successfully start the car. However,after I drive the car for 15 minutes, the light comes back on again anddoesn't turn off until I turn the car off. This is not normal. WhenI start the car again, it will stay off again for a few minutes.I have seen a number of explanations for this:1) bad oxygen sensor (replace sensor)2) problems with the solder connections on the main relay (replacerelay or re-solder all connections)3) put fuel injector cleaner in the tank or get injectors cleanedI understand the ECU might help me figure it out. But then I alsounderstand that the ECU is sometimes mistaken.Any help would be much appreciated. My car stalled out today. I thinkit was due to a problem with the ground wires but I'm still prettyconcerned.

Actually, my Integra's factory shop manual shows it under a section called "Fuel and Emissions".

It's under the backseat drivers side ashtrays. No need to pull the panel off. Just remove backseat passenger ashtray.

Its under Drivers side back seat astray. All you do is remove the ashtray. You ll be able to see the flashes without disassembling anything.
