I don't really get that one. I've got a '89 & I've never heard of that one. The LH control unit is what turns the lamp on, so how can it have a faulty signal from itself? I gotta check in my manual. I'm not ready to rule out EZK yet.
The LH control unit is what stores the fault codes, and they all have something to do with the LH (fuel injection). The EZK (ignition) can turn the check-engine light on, but it can't store a code into the LH ECU.
There are several connections between the LH & the EZK systems. Maybe if one is loose or dirty, the 5 blinks means the EZK thinks its getting a faulty signal from the LH. The EZK controller lives in the LH fender, roughly opposite the windshield washer fluid. Black box with a large electrical connector on the bottom. Unplug it (with the key TURNED OFF) & check if its dirty. Maybe try some contact cleaner or something?
If it wasn't so severe I might suspect spark plug wires, distributor cap & rotor, etc. But you might want to start it after dark & look for arcing on those things. Especially when you try to rev the engine.
