I have a 2012 Chevy Equinox LT that started reporting code p1443, and has started to die from time to time. This happens when the Equinox is at rest, either in gear or in "Park," then begins moving in either Drive or Reverse. The engine makes no sounds when it dies, it just dies as smoothly as if I turned the engine off myself. The engine will rev up to 3k-4k RPM while in Park without issue.
A few good revs and the problem temporarily goes away. I've replaced the evap purge solenoid so far, but it didn't fix the issue.
How should I go about troubleshooting the problem?
