Random stalling

Blindedlegacy · 04-04-2012, 12:31 AM

found time to let the car run. and do some test and here are some notes

alt is only putting out 12.66v at idle and head lights are on after 20 plus mins of running. bat is at 12.55

at about 2k rpm its around 13.5v (couldnt check battery)

car dies as if fuel pump has been cut off (unplugged the relay and it died like ive been describing)

fuel pump resistor pack has 1 ohm of resistance and spec says .7

main relay has 70 ohm of resistance.(guess thats normal because i tested another one)

car is only missing at idle (held the engine at about 2k no missing. unplugged the tps and no missing)

did the wiggle test on harness that is exposed and no change.( the airflow meter area, fuse box area, and hole in firewall)

i believe its not throwing that code because like i was saying the ecu might be messing up and i didnt get around to that because its dark. and questions?
