2010 chevy equinox 2.4l 48k miles. Just bought it recently from a hole in the wall dealership.

I am having intermittent problems with the vehicle stalling/trouble cranking.
With the vehicle in the on position but not running check engine light will click off and temp guage drop intermittently.
When vehicle is running idling or driving it will stall sometimes and other times drive fine.
It seems like the heat affects it because I work during the night and when I go to work I usually don't experience the problem.

I brought it to the dealership and they replaced the fpcm and the TCM.

Codes that have appeared are u0100,p0700,p069e after cleared 4 days later p069e,p023f after clearing u0100,p023f and finally one day later after clearing p0700,u0100.

It's been 2 days since I cleared the codes. The problem has happend a good amount of times with no codes set yet. The check engine light will click on and off randomly with either rpm/temp guage will drop when running or just the temp guage will drop when in the on position.

Other problems vehicle fails emissions test evap pressure sensor reading 16000kpa insanely high I haven't been able to get any information on this.
