Q: Car shuts off on idle

asked by on November 26, 2016

Hi,

I've invested quite a bit in replacing parts on this vehicle and out of the handful of problems I'm left with one that has been there for about 3 months. Normally at idle, or below 1.2k RPM the car will shut off. About 1 out of every 80 idles, but it's starting to happen multiple times per day now. Sometimes it will start on its own immediately after but sometimes it requires a jump. After a jump the car feels revitalized with handling and driving; it's odd. I've tested the battery voltages and with AC on full, lights on, accessories on and engine fans on the battery is still testing at 13.04V - 14.75V so I believe the alternator is working. At rest, ignition off, the battery is constantly between 12.6V-12.8V. I'm not getting an engine code from the computer. I've checked the drive belts and replaced them all are functioning properly now. I'm left with fuel delivery or idle engine processes... Help! :-) Please and thank you.
