96 Civic d16y7 Idle issue
So yesterday i was driving around on a sunny day(was not a hot sunny day just warm)... i stopped at a light and the car started to have ruff idle and just dropped and it battery light came on then it rose idle right before dieing.. No Check engine lights were on, oil was good.. any ideas??
it starts and runs okay, idle is high when cold but then settles down, i drove it today and it seemed fine but sometimes it will drop idle a little lower than it should then stays fine.. idk why it did yesterday.. it was the first time its happened to the point of dying
Sounds like either an ignition problem or the A/F ratio is off. Does the problem get worse as the engine heats up? First, replace any regular maintenance parts that are due, then test the resistance between clean bare metal on the valve cover and the negative battery terminal. Do the same test with bare metal on the thermostat cover. Ideally, there should be no resistance. Next, try cleaning the TB and IACV. After that, check for vacuum leaks and test the fuel pressure. If they check out fine, warm the car up well and try testing the ignition with either a spark tester or a new spark plug.
