I have a 1991 honda civic hatchback. The car runs great until it reaches normal running temperatures it starts to run like crap, it feels as if its running out of gas or stalling out. If u let it run it won't die it keeps running bad. I've changed the O2 sensor and checked my ecu an still nothing. The ecu blinks once. Does anyone have any suggestions?

Replace the Ignition Control Module (ICM) and coil:

I changed the coil but I don't know where the icm is and now the car wonnt start unless I push start it. Does anyone know where the ignition control module is??

It's located inside the distributor, attached to a heat sink.

So is it located underneath the coil after you take the cap off? And I forgot to mention that when the car starts to run bad I can turn on my headlights and fan and it will go back to running good but only for a limitted time and runs like crap until the car cools down. I know that there is a short in the headlight circuit from when the tachometer was removed by previous owner. Any idea if this makes a difference or just a weird occurrence
