  1. UPDATE! After much time diagnosing with my laptop scan tool, I was able to prevent the 2014 Spark from stalling during initial acceleration and dying when coming to an idle. I discovered that when I turned the fuel control loop off the car would idle and run perfect. As a temporary fix to treat the symptoms and keep from getting in or causing an accident, I unplugged the upstream O2 sensor. It has been about 2 weeks and the car has been running great. I know this is just a temp fix and I still need to find out why this causes the car to run perfect. The O2 sensor was the first item I changed
  2. Can someone post a diagram of the Component Locations of all the sensors for the 2014 Spark 1.2L? Pleeeease?
  3. I have a 2014 Chevrolet Spark with the stalling issue. The dealer claims it is not under warranty due to the title being "reconditioned". Regardless of the title concerns it still has a stall issue. Immediately after startup it idles and accelerates just fine. One to two minutes after start up the engine will stall out under acceleration as if running way to lean. Sometimes it back fires and some times not. If I rapidly press and release the acclerator it jerks a little but will not stall. If I throw it in neutral and put full accelerator the engine stops at 4000 rpms and will decline to about
