Ok, I have been fighting some electrical gremlins.
74 2.0L FI 037 brain (now with 270 ohm ballast resistor) The car runs great for 10-15 minutes then dies. I tested the power relay and fuel pump relay and fuel pump itself and have power to all. After it cools off for 3-5 minutes it will start again. I have not checked for spark, but am guessing when it dies this is what is stopping. What could this be??? ECU / Brain / Computer? I know they rarely fail When I unplug my air intake sensor it has no affect on running. I thought maybe another sign of potentially a bad ecu / brain / computer. I have read it is supposed to richen the mixture. Here is a pic of my car just because I like threads with pictures.  |

coil, and they do go bad. runs fine cold, as engine warms up, coil expands,windings separate discharge breaks down. cheap easy check before getting into chasing sparks in the dark, swap coils and rule it out first.
