Cavalier Stalls in Hot Weather
I have a 2008 Cavelier that runs great in temperatures under 90 F. However, in temperatures above 90 F, it stalls (runs really rough, then stalls) when foot is taken off the accelerator (slowing down to turn, stop, etc.). If I press the accelerator to the floor, it sometimes starts again, but runs really rough and then dies. The car will only run again if you let it sit 15 to 30 minutes.
I have replaced: Crankshaft position sensor, fuel filter & fuel pump. I have tested for spark right after the car dies and no issues there.
