ok, so i own a 89 civic hatch, with zc swap.
i recently changed the battery and alternator because the battery wasnt charging correctly and it would randomly die on me if it wasn't revved up at all(concluded that it was just a parasitic draw). i went through all my grounds and they all read .03-.04 amps, which is normal. i also cleaned up the grounds on the neg. batt. post and cable, and the grounds from the chassis to the valve cover. battery voltage is at 11.95V right now, and i can't figure anything out. once again, the battery and alternator are brand new, all grounds good, the belt tension is good, and when at idle the car will die and NOT start up

help me out!!

Your battery voltage should be about 12.5V when the engine is not running. What is the voltage with the engine running?

Have you cleaned the IACV?

 

i cleaned out the IACV with some carb cleaner and let it dry for an hour, and its still doing the same thing. also adjusted the throttle cable so it has a little less slack, and it no longer pulses the idle, but it'll still die. im so stuck

 

Try letting the car idle and turn the headlights and blower fan on. Does the car sputter and die?

If yes then id say its the electric load detector, built into your under the hood fuse box. You will need to swap out the entire fuse panel - its oober cheap on ebay for a replacement

 

okay, i will try that today at my buddies house today(he has jumper cables). still gotta keep the rpms up for voltage to my battery. i'll let you guys know if it works

 

car does sputter and die under full load(blower and lights ON)
i guess its time to replace the ELC

 

new fuse board worked, thanks guys
