Sounds to me like an ignition problem. Increased heat can cause increased resistance, which can cause unburnt fuel. I would start with a basic tune up. Cap, rotor, spark plugs, spark plug wires, fuel and air filter(s) would be a good start. Also, check all of your electrical connections and grounds. Check your fuel pressure regulator as well.
If you haven't replaced these normal maintenance items recently, you owe it to your car to do so. The '86 MY utilised LH 2.2 fuel injection which is fairly basic in nature. Moreover, the up-shift light is completely independent of the LH control unit. It was not until LH 2.4 and on that the up-shift light was incorporated into the ECU.
Don't lose sight of the big picture, and just assume your ECU went haywire. Unless someone has fussed with the ECU in the past, the odds are that that's not your cause.
